I was looking at Menuhin & Grappelli Play Berlin, Kern, Porter & Rodgers & Hart and I saw there is no genre information:
However the mbgenres plugin for beets classifies this release with the genres “classical;jazz” which feels about right to me.
However I have no idea where this system gets this info from. Maybe from a source other than MusicBrainz? Or from some other MusicBrainz page/api?
So my question here: Does MusicBrainz store somewhere else some other “hidden” genre information?
Genre probably came from the artists. As I understand it, if no genre on Release it checks Release Group and then Artists until it finds something it can use.
there can also be genres set in the recordings of a release
that said, I wonder why it pulled jazz and not gypsy jazz, because in all the cases I’ve seen (recordings and Stéphanie Grappelli), the latter has equal or more votes… I’m wondering if the genres are from a different source, or perhaps processed to give genres and styles (or subgenres), like Discogs uses
I’m not familiar with beets, but what is “mngenres” i cant see that listed here, only the lastgenre plugin LastGenre Plugin — beets
Aha, good point! Will need to do some digging in this direction!
Sorry @sound.and.vision, I misstyped it: It is called “mbgenres” and it is a 3rd party plugin from mistwyrm/BeetsPlugins.
From the plugin page:
True, fetches genres from the release artist if no genres are found at the release or release group level. Default: True.Artist ID would be part of it. I never did test the feature with multiple artists, but looking at the beets database it looks like it just stores the MBID for the first artist credited anyway. So for that release it’d just get “classical” from Yehudi Menuhin.
I would guess the “jazz” tag was already on the release. With default settings the plugin doesn’t replace genres, so if the jazz genre was already there, it’d just add the classical one to it.
