Ipod touch 5 doesn't play music not purchased
I tried everything. I restore my iPod to not just on back up, but I even restored it to manufacturer/brand new. I tried manually dragging my music, and I tried syncing it. I thought it was space but this is a 32 GB ipod touch, and I've had doubled the music before than I'm trying now, and it's still not working. I'm so fustrated with this. And of course it happens just yesterday, after the last update. I dreally don't know what's wrong. Everything else is fine.
iPod touch, iOS 7.1
