OK, that's what I guessed it meant, which is great because I've been wanting to shuffle by album. But it took me a while to figure out how to do it (I hadn't when I first started writing this). For anyone else: I had to go to library -> Albums -> long press on any album -> play. Then, in the player, step through the shuffle options until you get to shuffle lists. What doesn't work is going to Library -> Albums -> Menu -> Shuffle -> change to shuffle lists... if you do that it doesn't remember that you were browsing by album - when you select shuffle from the menu while in the Library it seems to reset your 'top level sort order' to all songs. It might be nice to have a way to select the different shuffle options directly from the library view. EDIT: OK, my method for shuffling albums doesn't quite work, because although it will go to another randomly chosen album if you do a "big" skip ahead, if you just let the album play out it stops. So I still don't know how to really get it to continuously play random albums.
