I got my iPhone 5 last week and activated it this past weekend. Of course, I rolled over all of my info from my old iPhone to this one and entered all of my information in the necessary areas including my Apple ID. Now when ever I go to my music app and try to play something, a popup comes up asking for my Apple ID password and I have no idea why. I usually hit cancel and go along my merry way and be done with it until next time. So the questions are, why is this happening? What in the music app is my Apple ID needed for? And is there something in System Settings that I have on that constantly needs this info? Thanks.
