Okay

I dont know if its the app, or just my phone or earbuds, but Ill click play on songs in my playlist and they wont play unless I delete and re-download the app.
And to all the people saying you cant play music and exit the app, or play music while your phone is locked, you either double click your home button if its locked, or swipe up and there should be a play button. Simple as that. You can use that trick with YouTube as well.
