MusicBrainz metadata

Starting in v13 "Gotham", Kodi has "MusicBrainzID" integration. This allows your music metadata to be updated automatically when that data is updated on the MusicBrainz database if the music has MusicBrainz ID tags.


 * MusicBrainz tag reading/online overriding is enabled by default. The setting for this can be found in Settings -> Music -> Library -> Override song tags with online information


 * The new behavior goes as follows


 * If you don't have MusicBrainz tags and you have the option turned off, you should see the exact same as you saw in v12 Frodo.
 * If you don't have MusicBrainz tags and you have the option turned on, you should see the exact same as you saw in v12 Frodo.
 * If you have MusicBrainz tags and you have the option turned off, you should see the exact same as you saw in v12 Frodo.
 * If you have MusicBrainz tags and you have the option turned on, you should get dynamic metadata from MusicBrainz. i.e. once you've MusicBrainz tagged your files once, your library and metadata is built dynamically from up-to-date MusicBrainz data, and later kept up-to-date and refreshed automatically so you always have good tags.

NFO files
Like with most metadata in XBMC, MusicBrainz tags can be added using NFO files. Both album.nfo and artist.nfo files can contain the MusicBrainz tag or simply contain a URL to the correct page on the MusicBrainz website, similar to how Movies can contain an IMDb URL NFO file.
