hi there when I try to play a song on spotify it does not work anymore. I think that the point is that Itunes is still on. For example when I listen to the music with headphones on spotify, I push the botton on the headphones cable and the song on Itunes starts, even if I am on spotify. Does anyone know the solution?
Try double tapping the home button, holding down over the music app, and then pressing the little round "Stop" button in the corner. This should close down "Music" for the time being, and you should be able to just control Spotify using the button on your headphones.
