Some how nokia music stop their service for US couple days ago.
just found away to go around it, delete/log out your Nokia account will do. Tried on all 7 Att 920 and 100% successful.
Maybe that's my issue. I don't have a Nokia account. What, exactly IS a Nokia account?
actually my solution is deleting Nokia account on my phone, and everything came back online. I tried on half a dozen of 920 and they all work. Give it a try.
