I found a bug that is present in 1.11 and 1.12. To reproduce:
1) Play a single album from an artist that you have SEVERAL albums for.
2) While in media player screen, click top bar to bring up all albums by that artist
3) Drill down to one of those albums until you see all songs for that album displayed.
4) Click PLAY.
5) ISSUE: *all* albums for that artist are added to the queue, not just the one album you intended on playing.
This USED TO WORK before, I am 100% sure!!!!
