What's making Apple Music Hang?

So I upgraded to iOS 8.4. Promptly hid Apple Music under settings. Now my music player keeps on freezing/hanging. Sometimes it just stops mid-stream while playing a song (most stream off iTunes match). Sometimes it just won't respond to the pause button. Sometimes it'll just hang and kick me back to the homescreen. This is probably the worst upgrade I've ever seen of an application, it makes me fear *any* upgrade from Apple since you can't roll it back. Any ideas?
