I might be missing it if it's already there.... It would be nice to have an option in the U.I. menu to disable this button from showing on the play screen. I find that I may often touch this button when I want to switch tracks, especially when I am driving, as I don't take my eyes off the road (or I try not to). Kinda frustrating to go from Disturbed to Classical by a mis-press. Wouldn't be too bad if I could go back to one list (genre) without resetting the list. (that's a whole other topic) All in all, very nice app. Well worth the money, and I recommend it to all my friends.
