Falling in love with AirPlay (with various interweb stations). While people are testing, mind if I ask current model AppleTV owners if audio AirPlay streaming with iPhone or iPad keeps an interface going on the iDevice (normal iTunes, etc.) not blank out (with simple controls) as video streaming appears to do in Apples AirPlay vids? Trying to decide between an AppleTV or another AirPort Expess and for this use may not have a TV turned on when playing music.
