This app is wonderful, but when I updates to ios 8, some of my songs crashes it. I found the way to fix this is to make sure the song you want to hear HAS album artwork. The ones that dont will probably crash you. I tested it myself, and now my music works just fine. An official patch would be nice, but until then, make sure your songs have album artwork
