ipad music player crash
You might need to isolate the problem further.


Syncing with iTunes will rebuild the iTunes database files and potentially correct artwork problems.
playing new content might show that the existing content is in some way corrupt.
backing up the device and erasing all content and settings might be a more drastic step to get a clean song or two.


If that crashes, restore your device. If not, you can restore the backup and continue isolating things that will cause the crash. There's no update for iTunes, but perhaps you just need to wait for iOS 8.2 to arrive if it's not anything you are causing. The fact that multiple songs cause a crash means it's more likely about the database file storing the playlists and not just a bad song or two. Your comment about it happening with music that once played fine also points to settings and metadata and not the songs themselves.
