It maybe a Kinsky thing, but actually all songs do have an albumArtist, it just not shown for the object.item.audioItem.musicTrack displayed when you get details for a track
When you get details for a group (object.container.album.musicAlbum) it shows an albumArtist and an artist field, but the value shown for albumArtist is actually the (track) artist.
When you get details for an actual album (object.container.album.musicAlbum) it lists Artist and AlbumArtist, but both values are set to the value of albumArtist.

I will try out adding genres, but without genres Kinsky is not consisently showing composer instead of artist, it is only showing for groups and tracks within groups, and then only sometimes.

I'll also try out Kazoo
