strange bug in music player

having trouble in playing my music in itunes that was transferred from the computer. It has always been playing fine. Now, when a track is selected, it skips 7-8 songs and then lands on a random one and plays, skipping to the next track repeats the same cycle. It is really weird and just started happening. Itunes radio music skips forward fine. Hard reset on phone did not help Running iOS 7 beta 3. Any solutions?
