Can you be more specific - maybe we can talk in Kodi DB terms so that we mean the same things? If I understand it correctly, genres are assigned to songs, not to artists (in the table song_genre). Artists do not have genres assigned to them directly, you would have to look that up through a JOIN, and then it is quite possible that a single artist has multiple genres.
So my issue might be a parsing problem - either on Kodi or on Yatse side. Any individual song of the Space Night albums will have (amongst others) the following ID3 tags:
- Artist: (whatever the track artist is)
- Album artist: “Space Night”
- Genre: Electronica
This is being parsed by Kodi, and then the artist “Space Night” appears in the DB in the artist table (id 143), and is linked to several albums in the album_artist table. Of course it is also set as a string in several tables (e.g. strArtistDisp in album table).
I don’t know how Yatse (or Kodi) directly relates artists to genres (there is no table or view for that in the Music DB), but maybe this is only done for track artists, not album artists?
