Perhaps I'm misremembering but I'm pretty sure at one point I was able to go into genres, pick an album, and when that album was over (if I was in shuffle catergories and advance list is on) it would advance to another random album in that genre.
What it is currently doing is at the end of the album it will advance to another random album, not necessarily in the same genre. Same behavior if I press Next Category rather than letting the album finish.
If I go into Artists (for example) then it will play all of that artist's songs in song title order then advance to a different artist and play of that artist's songs in order. So the behavior between Artist and Album is different. (If you go into Songs the Next Category is disabled.) The behavior between Album and Genre is now identical (since it disregards Genre when shuffling).
In Genres -> Album
Shuffle: Shuffle Categories
Repeat: Advance List
Actual behavior: When album advances then play continues to another random album in any genre and will play that album in order in its entirety.
Expected behavior (I think): When album advances then play continues to another random album in the same genre and will play that album in order in its entirety.
