iPod won't play music? Updated to iOs 7?

Whenever I try to play music I'll go into the music app and I'll see all my songs and when I push play they don't play it waits a few seconds then skips to the next song, but the next song wont work so it'll keep skipping.

Then when I try to download the song (I don't know if its on icloud?) it says that "This device is already associated with an Apple ID, You can download past purchases with just one apple ID every 90 days. This device can be used with another apple ID in 15 days"

HELP? :/
