My starred tracks are downloaded onto my iPhone and I often listen to this while driving. The playlist often just STOPS when a song finishes and wont play the next one. I can open the phone and press the Next button to get it to the next song (Or the shuffle button again), and it often works for several songs before doing this again. I'm having a pretty big issue with this because I can't just grab my phone and press buttons on it while I'm driving. Does anyone know what's going on here?
