The Music app on the phone to total garbage. You can't transfer ANY music you downloaded to your old phone UNLESS you paid for it. Today on my 820 I had numerous issues just adding songs to songs that were already playing. When I tap+held the song title one of two things would happen: nothing (i.e. no contextual menu for doing anything with the song) OR it started playing the song and lost everything I had already been playing. I finally gave up and re-booted the phone manually. This app is horrid.
