I just upgraded to iOS 8 and now have a 6 Plus. I've noticed now that sometimes a song will be playing for maybe 30 seconds and then stop. After that, I tap on the song but nothing happens. It moves a bit so I know it senses the tap, but won't play. The only way I can work around this is to close the app out completely and go back in. I've searched around and haven't seen if anyone else is experiencing this. Has anyone? Thanks!
