music-downloader

This programm will first get the metadata of various songs from metadata provider like musicbrainz, and then search for download links on pages like bandcamp. Then it will download the song and edit the metadata according.

Metadata

First the metadata has to be downloaded. The best api to do so is undeniably Musicbrainz. This is a result of them being a website with a large Database spanning over all Genres.

Musicbrainz

To fetch from Musicbrainz 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.

Then we can output them in the Terminal and ask for further input. Following can be inputed afterwards:

q to quit
ok to download
.. for previous options
. for current options
an integer for this element

If the following chosen element is an artist, its discography + a couple tracks are outputed, if a release is chosen, the artists + tracklist + release is outputted, If a track is chosen its artists and releases are shown.

TO DO

Schow always the whole tracklist of an release if it is chosen
Show always the whole discography of an artist if it is chosen

Up to 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 . Following I fatch and thus 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 100% percicely all of the time, if it is known and the website has a search api for that. Obviously this will get important later.
