Music app sporadically crashing
iOS 9.2.1
iPhone 6
The music app has begun crashing sporadically within the past week. It will play about a minute into a song, then crash. When it recovers, it starts the same song over from the beginning. If I then skip the song (because I've already heard a fair portion), there's a high likelihood it will crash the same way during the next song (but this isn't always the case). It also crashes if I interact too much with the app while it's playing, or if I'm doing something with another app.
The frequency has gradually increased day to day, to where it will now crash at least a few dozen times in a day (I listen to it all day). This might have been triggered by my last iTunes sync, so I might try another sync to see if that helps. Any other suggestions for resolving this issue are most appreciated.
