## Classes and Objects
### music_kraken.objects
#### Collection
#### Song
So as you can see, the probably most important Class is the `music_kraken.Song` class. It is used to save the song in *(duh)*.
It has handful attributes, where half of em are self-explanatory, like `title` or `genre`. The ones like `isrc` are only relevant to you, if you know what it is, so I won't elaborate on it.
Interesting is the `date`. It uses a custom class. More on that [here](#music_krakenid3timestamp).
#### ID3Timestamp
For multiple Reasons I don't use the default `datetime.datetime` class.
The most important reason is, that you need to pass in at least year, month and day. For every other values there are default values, that are indistinguishable from values that are directly passed in. But I need optional values. The ID3 standart allows default values. Additionally `datetime.datetime` is immutable, thus I can't inherint all the methods. Sorry.
Anyway you can create those custom objects easily.
```python
from music_kraken import ID3Timestamp
# returns an instance of ID3Timestamp with the current time
ID3Timestamp.now()
# yea
ID3Timestamp(year=1986, month=3, day=1)
```
you can pass in the Arguments:
- year
- month
- day
- hour
- minute
- second

# Old implementation
> IF U USE THIS NOW YOU ARE DUMB *no offense thoug*. IT ISN'T FINISHED AND THE STUFF YOU CODE NOW WILL BE BROKEN TOMORROW
> SOON YOU CAN THOUGH
If you want to use this project, or parts from it in your own projects from it,
make sure to be familiar with [Python Modules](https://docs.python.org/3/tutorial/modules.html).
Further and better documentation including code examples are yet to come, so here is the rough
module structure for now. (Should be up-to-date, but no guarantees)
If you simply want to run the builtin minimal cli just do this:
```python
from music_kraken import cli
cli()
```
### Search for Metadata
The whole program takes the data it processes further from the cache, a sqlite database.
So before you can do anything, you will need to fill it with the songs you want to download (*or create song objects manually, but more on that later*).
For now the base of everything is [musicbrainz][mb], so you need to get the musicbrainz `id` and `type`. The `id` corresponds to either
- an artist
- a release group
- a release
- a recording/track).
To get this info, you first have to initialize a search object (`music_kraken.MetadataSearch`).
```python
search_object = music_kraken.MetadataSearch()
```
Then you need an initial "text search" to get some options you can choose from. For
this you can either specify artists releases and whatever directly with one of the following functions:
```python
# you can directly specify artist, release group, release or recording/track
multiple_options = search_object.search_from_text(artist=input("input the name of the artist: "))
# you can specify a query see the simple integrated cli on how to use the query
multiple_options = search_object.search_from_query(query=input("input the query: "))
```
Both methods return an instance of `MultipleOptions`, which can be directly converted to a string.
```python
print(multiple_options)
```
After the first "*text search*" you can either again search the same way as before,
or you can further explore one of the options from the previous search.
To explore and select one options from `MultipleOptions`, simply call `MetadataSearch.choose(self, index: int)`.
The index represents the number in the previously returned instance of MultipleOptions.
The selected Option will be selected and can be downloaded in the next step.
*Thus, this has to be done **after either search_from_text or search_from_query***
```python
# choosing the best matching band
multiple_options = search_object.choose(0)
# choosing the first ever release group of this band
multiple_options = search_object.choose(1)
# printing out the current options
print(multiple_options)
```
This process can be repeated indefinitely (until you run out of memory).
A search history is kept in the Search instance. You could go back to
the previous search (without any loading time) like this:
```python
multiple_options = search_object.get_previous_options()
```
### Downloading Metadata / Filling up the Cache
You can download following metadata:
- an artist (the whole discography)
- a release group
- a release
- a track/recording
If you got an instance of `MetadataSearch`, like I elaborated [previously](#search-for-metadata), downloading every piece of metadata from the currently selected Option is really quite easy.
```python
from music_kraken import fetch_metadata_from_search
# this is it :)
music_kraken.fetch_metadata_from_search(search_object)
```
If you already know what you want to download you can skip the search instance and simply do the following.
```python
from music_kraken import fetch_metadata
# might change and break after I add multiple metadata sources which I will
fetch_metadata(id_=musicbrainz_id, type=metadata_type)
```
The option type is a string (*I'm sorry for not making it an enum I know its a bad pratice*), which can
have following values:
- 'artist'
- 'release_group'
- 'release'
- 'recording'
**PAY ATTENTION TO TYPOS, IT'S CASE SENSITIVE**
The musicbrainz id is just the id of the object from musicbrainz.
After following those steps, it might take a couple seconds/minutes to execute, but then the Cache will be filled.
### Cache / Temporary Database
All the data, the functions that download stuff use, can be gotten from the temporary database / cache.
The cache can be simply used like this:
```python
music_kraken.test_db
```
When fetching any song data from the cache, you will get it as Song
object (music_kraken.Song). There are multiple methods
to get different sets of Songs. The names explain the methods pretty
well:
```python
from music_kraken import cache
# gets a single track specified by the id
cache.get_track_metadata(id: str)
# gets a list of tracks.
cache.get_tracks_to_download()
cache.get_tracks_without_src()
cache.get_tracks_without_isrc()
cache.get_tracks_without_filepath()
```
The id always is a musicbrainz id and distinct for every track.
### Setting the Target
By default the music downloader doesn't know where to save the music file, if downloaded. To set those variables (the directory to save the file in and the filepath), it is enough to run one single command:
```python
from music_kraken import set_target
# adds file path, file directory and the genre to the database
set_target(genre="some test genre")
```
The concept of genres is too loose, to definitely say, this band exclusively plays this genre, or this song is this genre. This doesn't work manually, this will never work automatically. Thus, I've decided to just use the genre as category, to sort the artists and songs by. Most Music players support that.
As a result of this decision you will have to pass the genre in this function.
### Get Audio
This is most likely the most useful and unique feature of this Project. If the cache is filled, you can get audio sources for the songs you only have the metadata, and download them. This works for most songs. I'd guess for about 97% (?)
First of you will need a List of song objects `music_kraken.Song`. As [mentioned above](#cache--temporary-database), you could get a list like that from the cache.
```python
# Here is an Example
from music_kraken import (
cache,
fetch_sources,
fetch_audios
)
# scanning pages, searching for a download and storing results
fetch_sources(cache.get_tracks_without_src())
# downloading all previously fetched sources to previously defined targets
fetch_audios(cache.get_tracks_to_download())
```
*Note:*
To download audio two cases have to be met:
1. [The target](#setting-the-target) has to be set beforehand
2. The sources have to be fetched beforehand
---
## Metadata
First the metadata has to be downloaded. The best api to do so is undeniably [Musicbrainz][mb]. This is a result of them being a website with a large Database spanning over all Genres.
### Musicbrainz
![Musicbrainz Data Scheme](https://wiki.musicbrainz.org/-/images/9/9e/pymb3-model-core.png)
To fetch from [Musicbrainz][mb] we first have to know what to fetch. A good start is to get an input query, which can be just put into the MB-Api. It then returns a list of possible artists, releases and recordings.
If the following chosen element is an artist, its discography + a couple tracks are printed, if a release is chosen, the artists + tracklist + release is outputted, If a track is chosen its artists and releases are shown.
For now, it doesn't if the discography or tracklist is chosen.
### Metadata to fetch
I orient on which metadata to download on the keys in `mutagen.EasyID3`. The following I fetch and tag the MP3 with:
- title
- artist
- albumartist
- tracknumber
- albumsort can sort albums cronological
- titlesort is just set to the tracknumber to sort by track order to sort correctly
- isrc
- musicbrainz_artistid
- musicbrainz_albumid
- musicbrainz_albumartistid
- musicbrainz_albumstatus
- language
- musicbrainz_albumtype
- releasecountry
- barcode
#### albumsort/titlesort
Those Tags are for the musicplayer to not sort for Example the albums of a band alphabetically, but in another way. I set it just to chronological order
#### isrc
This is the **international standart release code**. With this a track can be identified 99% of the time, if it is known and the website has a search api for that. Obviously this will get important later.
## Download
Now that the metadata is downloaded and cached, download sources need to be sound, because one can't listen to metadata. Granted it would be amazing if that would be possible.
### Musify
The quickest source to get download links from is to my knowledge [musify](https://musify.club/). It's a Russian music downloading page, where many many songs are available to stream and to download. Due to me not wanting to stress the server to much, I abuse a handy feature nearly every page where you can search suff has. The autocomplete api for the search input. Those always are quite limited in the number of results it returns, but it is optimized to be quick. Thus with the http header `Connection` set to `keep-alive` the bottleneck definitely is not at the speed of those requests.
For musify the endpoint is following: [https://musify.club/search/suggestions?term={title}](https://musify.club/search/suggestions?term=LornaShore) If the http headers are set correctly, then searching for example for "Lorna Shore" yields following result:
```json
[
{
"id":"Lorna Shore",
"label":"Lorna Shore",
"value":"Lorna Shore",
"category":"Исполнители",
"image":"https://39s.musify.club/img/68/9561484/25159224.jpg",
"url":"/artist/lorna-shore-59611"
},
{"id":"Immortal","label":"Lorna Shore - Immortal (2020)","value":"Immortal","category":"Релизы","image":"https://39s-a.musify.club/img/70/20335517/52174338.jpg","url":"/release/lorna-shore-immortal-2020-1241300"},
{"id":"Immortal","label":"Lorna Shore - Immortal","value":"Immortal","category":"Треки","image":"","url":"/track/lorna-shore-immortal-12475071"}
]
```
This is a shortened example for the response the api gives. The results are very Limited, but it is also very efficient to parse. The steps I take are:
- call the api with the query being the track name
- parse the json response to an object
- look at how different the title and artist are on every element from the category `Треки`, translated roughly to track or release.
- If they match get the download links and cache them.
### Youtube
Herte the **isrc** plays a huge role. You probably know it, when you search on youtube for a song, and the music videos has a long intro or the first result is a live version. I don't want those in my music collection, only if the tracks are like this in the official release. Well how can you get around that?
Turns out if you search for the **isrc** on youtube the results contain the music, like it is on the official release and some japanese meme videos. The tracks I wan't just have the title of the released track, so one can just compare those two.
For searching, as well as for downloading I use the programm `youtube-dl`, which also has a programming interface for python.
There are two bottlenecks with this approach though:
1. `youtube-dl` is just slow. Actually it has to be, to not get blocked by youtube.
2. Ofthen musicbrainz just doesn't give the isrc for some songs.
## Lyrics
To get the Lyrics, I scrape them, and put those in the USLT ID3 Tags of for example mp3 files. Unfortunately some players, like the one I use, Rhythmbox don't support USLT Lyrics. So I created an Plugin for Rhythmbox. You can find it here: [https://github.com/HeIIow2/rythmbox-id3-lyrics-support](https://github.com/HeIIow2/rythmbox-id3-lyrics-support).
### Genius
For the lyrics source the page [https://genius.com/](https://genius.com/) is easily sufficient. It has most songs. Some songs are not present though, but that is fine, because the lyrics are optional anyways.

# music_kraken.objects
## DatabaseObject
[music_kraken.objects.DatabaseObject](../src/music_kraken/objects/parents.py)
This is a parent object, which most Music-Objects inherit from. It provides the **functionality** to:
- autogenerate id's *(UUID)*, if not passed in the constructur.
- [merge](#databaseobjectmerge) the data of another instance of the same time in self.
- Check if two different instances of the same type represent the same data, using `__eq__`.
Additionally it provides an **Interface** to:
- define the attributes used to [merge](#databaseobjectmerge).
- define the attribuse and values used to check for equal data. *(used in `__eq__` and in the merge)*
- get the id3 [metadata](#metadata).
- get all [options](#options) *(used in searching from e.g. the command line)*
### DatabaseObject.merge()
To merge the data of two instances of the same type, the attributes defined in `DatabaseObject.COLLECTION_ATTRIBUTES` and `SIMPLE_ATTRIBUTES` are used.
The simple attributes just get carried from the other instance, to the self instance.
The collection attributes appends all elements from other.collection to self.collection, but ofc [checks if already exists](#collection).
## Collection
[music_kraken.objects.Collection](../src/music_kraken/objects/collection.py)
This is an object, which acts as a list. You can save instaces of a subclass of [DatabaseObject](#databaseobject).
Then you can for example append a new Object. The difference to a normal list is, that if you have two different objects that both represent the same data, it doesn't get added, but all data gets [merged](#databaseobjectmerge) into the existing Object instead.
For example, you have two different Artist-Objects, where both have one source in common. The one Artist-Object already is in the Collection. The other artist object is passed in the append command.
In this case it doesn't simply add the artist object to the collection, but modifies the already existing Artist-Object, adding all attributes the new artist object has, and then discards the other object.
```python
artist_collection = Collection(element_type=Artist)
# adds the artist to the list (len 1)
artist_collection.append(artist_1)
# detects artist 2 has a mutual source
# thus not adding but mergin (len 1)
artist_collection.appent(artist_2)
```
Function | Explanation
---|---
`append()` | appends an object to the collection
`extend()` | appends a list of objects to the collection
`__len__()` | gets the ammount of objects in collection
`shallow_list` | gets a shallow copy of the list `_data` the objects are contained in
`sort()` | takes the same arguments than `list.sort`, and does the same
`__iter__()` | allows you to use collections e.g. a for loop
## Options
## Metadata
## Song
This object inherits from [DatabaseObject](#databaseobject) and implements all its interfaces.
It has handful attributes, where half of em are self-explanatory, like `title` or `genre`. The ones like `isrc` are only relevant to you, if you know what it is, so I won't elaborate on it.
Interesting is the `date`. It uses a custom class. More on that [here](#music_krakenid3timestamp).
## ID3Timestamp
For multiple Reasons I don't use the default `datetime.datetime` class.

For every other values there are default values, that are indistinguishable from values that are directly passed in. But I need optional values. The ID3 standart allows default values. Additionally `datetime.datetime` is immutable, thus I can't inherint all the methods. Sorry.
Anyway you can create those custom objects easily.
```python
from music_kraken import ID3Timestamp
# returns an instance of ID3Timestamp with the current time
ID3Timestamp.now()
# returns an instance of ID3Timestamp with the given values
# all values are optional if unknown
ID3Timestamp(year=1986, month=3, day=1, hour=12, minute=30, second=6)

Thus with the http header `Connection` set to `keep-alive` the bottleneck definitely is not at the speed of those requests.
For musify the endpoint is following: [https://musify.club/search/suggestions?term={title}](https://musify.club/search/suggestions?term=LornaShore) If the http headers are set correctly, then searching for example for "Lorna Shore" yields following result:
```json
[
{
"id":"Lorna Shore",
"label":"Lorna Shore",
"value":"Lorna Shore",
"category":"Исполнители",
"image":"https://39s.musify.club/img/68/9561484/25159224.jpg",
"url":"/artist/lorna-shore-59611"
},
{"id":"Immortal","label":"Lorna Shore - Immortal (2020)","value":"Immortal","category":"Релизы","image":"https://39s-a.musify.club/img/70/20335517/52174338.jpg","url":"/release/lorna-shore-immortal-2020-1241300"},
{"id":"Immortal","label":"Lorna Shore - Immortal","value":"Immortal","category":"Треки","image":"","url":"/track/lorna-shore-immortal-12475071"}
]
```
This is a shortened example for the response the api gives. The results are very Limited, but it is also very efficient to parse. The steps I take are:
- call the api with the query being the track name
- parse the json response to an object
- look at how different the title and artist are on every element from the category `Треки`, translated roughly to track or release.
- If they match get the download links and cache them.
### Youtube
Herte the **isrc** plays a huge role. You probably know it, when you search on youtube for a song, and the music videos has a long intro or the first result is a live version. I don't want those in my music collection, only if the tracks are like this in the official release. Well how can you get around that?
Turns out if you search for the **isrc** on youtube the results contain the music, like it is on the official release and some japanese meme videos. The tracks I wan't just have the title of the released track, so one can just compare those two.
For searching, as well as for downloading I use the programm `youtube-dl`, which also has a programming interface for python.
There are two bottlenecks with this approach though:
1. `youtube-dl` is just slow. Actually it has to be, to not get blocked by youtube.
2. Ofthen musicbrainz just doesn't give the isrc for some songs.
## Lyrics
To get the Lyrics, I scrape them, and put those in the USLT ID3 Tags of for example mp3 files. Unfortunately some players, like the one I use, Rhythmbox don't support USLT Lyrics. So I created an Plugin for Rhythmbox. You can find it here: [https://github.com/HeIIow2/rythmbox-id3-lyrics-support](https://github.com/HeIIow2/rythmbox-id3-lyrics-support).
### Genius
For the lyrics source the page [https://genius.com/](https://genius.com/) is easily sufficient. It has most songs. Some songs are not present though, but that is fine, because the lyrics are optional anyways.
