**Genre:** First the cli asks you to input a gere you want to download to. The options it gives you (if it gives you any) are all the folders you got in the music directory. You also can just input a new one.
**What to download:** After that it prompts you for a search. Here are a couple examples how you can search:
After searching with this syntax it prompts you with multiple results. You can either choose one of those by inputing its id `int` or you can search for a new query.
After you chose either an artist, a release group, a release or a track by its id, download it by inputing the string `ok`. My downloader will download it automatically for you.
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.
### Musicbrainz
To fetch from [Musicbrainz](musicbrainz.org/) we first have to know what to fetch. A good start is to get an input querry, 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.
- 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
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.
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.
The quickest source to get download links from is to my knowledge [musify](https://musify.club/). Its 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 defently 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:
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:
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.
