Made my songs available offline, they're showing as downloaded but won't play or on the artists page it says "nothing to see" I've paid for this and it does it on a regular basis now!! Nothing but problems since I got it, and I live in a remote area in the middle of nowhere so wifi isn't the answer so I really on my offline music for a little bit of sanity!!
Same, I am getting the same problem from a month or two. I have an ipod touch a 5th gen model. I also uninstalled it and Reinstalled it two or three times but no use. I got a premium subscription since last year and I never had this problem. Is Annoying as hell.
