I use my iPhone a lot to listen to music on, and a lot of times when I pick a song to listen to and then lock the screen the song stops playing a second later. And when I unlock the screen to start it playing again it still shows that it is playing even though the music is paused. This becomes a nuisance because it has happened countless times. While it isn't a big deal, I would like to know if anyone has a fix or if this has happened to anybody else.
