### Search for Metadata
The whole programm 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.
For now the base of everything is musicbrainz, so you need to get the
musicbrainz id and the type the id corresponds to (artist/release group/release/track).
To get this you first have to initialize a search object (`music_kraken.metadata.metadata_search.Search`).

To get this info, you first have to initialize a search object (`music_kraken.MetadataSearch`).

search_object = mk.metadata.metadata_search.Search()

### Downloading Metadata / Filling up the Cache
If you selected the Option you want with `Search.choose(i)`, you can
finally download the metadata of either:
You can download following metadata:
- an artist (the whole discography)
- a release group
- a release
- a track/recording
To download you need the selected Option Object (`music_kraken.metadata.metadata_search.Option`)
it is simply stored in `Search.current_option`.
If you already know what you want to download you can skip all the steps above and just create
a dictionary like this and use it later (*might change and break after I add multiple metadata sources which I will*):
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
download_dict = {
'type': option_type,
'id': musicbrainz_id
}
from music_kraken import fetch_metadata_from_search
# this is it :)
music_kraken.fetch_metadata_from_search(search_object)
```
The option type is a string (I'm sorry for not making it an enum I know its a bad pratice), which can
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, ITS CASE SENSITIVE**
The musicbrainz id is just the id of the object from musicbrainz.
```python
# in this example I will choose the previous selected option.
option_to_download = search_object.current_option
print(option_to_download)
download_dict = {
'type': option_to_download.type,
'id': option_to_download.id
}
```
If you got the Option instance you want to download and created the dictionary, then downloading the metadata is really straight
forward, so I just show the code.
```python
# I am aware of abstrackt classes
metadata_downloader = mk.metadata.metadata_fetch.MetadataDownloader()
metadata_downloader.download(download_dict)
```
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.
You can get the database object like this:
The cache can be simply used like this:
```python
cache = mk.database.temp_database.temp_database
print(cache)
music_kraken.cache
```
When fetching any song data from the cache, you will get it as Song
object (music_kraken.database.song.Song). There are multiple methods

to get different sets of Songs. The names explain the methods pretty

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
mk.target.set_target.UrlPath(genre="some test genre")
set_target(genre="some test genre")
```
The concept of genres is too loose, to definitly 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 (*actually its a class but it doesn't make any difference*).

### Get the Download Links / Audio Sources
### Get Audio
This is most likely the most usefull and unique feature of this Project. If the cache is filled you can get audio sources for the songs you only have the metadata. This works for most songs. I'd guess for about 97% (?)
This is most likely the most usefull 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
# this is how you do it.
mk.audio_source.fetch_source.Download()
# 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())
```
Now the audio sources are int the cache, and you can get them as mentioned above (`Song.sources: List[Source]`).
### Downloading the Audio
If the target paths fields and audio sources are set in the database field, then the audio files can just be downloaded and automatically tagged like this:
```python
mk.audio_source.fetch_audio.Download()
# after that the lyrics can be added
mk.lyrics.lyrics.fetch_lyrics()
```
*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](musicbrainz.org/). This is a result of them being a website with a large Database spanning over all Genres.
