Music playback troubles

Hi,

After turning on my ipad 2 wifi+3g this morning, i tried to play a song but nothing happened, i kept pressing play/skip/pause and still nothing.....sometimes when i press a song from the music app list it plays a completelydifferent song and soemtimes even a completely different track name/info...

This is really not good because i cant listen to any music.....i have tried closing the app, stopping the app and restarting the ipad by holding the lock and home button, and still nothing works...

Any ideas?

Thanks, Jordan
