Currently, I can create a grouping hierarchy like:
Level 1: Year - Album
Level 2: Artist
However, I cannot create a grouping hierarchy in the following order:
Level 1: Year - Artist - Album
This would be useful for users with compilation albums, soundtracks, or large music collections where browsing by year and artist before album is preferred.
It should be possible to create a grouping hierarchy such as:
Year, Artist, Album
Additionally, it would be useful to allow ascending and descending sorting for grouping levels independently.
