iPhone skipping through songs

Hello all, recently, when I try to play music on either the Grooveshark app or the Music app certain songs will play for exactly 20 sec then a short screech comes through the speakers and it moves to the next song. Any suggestions on how I can fix this?

Thanks for any and all help!
