I'm not sure but it may be caused by the heavy base causing the record to skip. The T:L soundtrack is very base heavy. You could play the soundtrack from a CD/mp3 and see if the same thing happens. If it does, it's either your receiver or speakers, if not, then it's the turntable. That should help you narrow down the problem. How close is your turntable to the speakers, what kind of speakers are you using, are you using a sub, etc.
By the way, I started this thread a while ago

Hopefully we can fix your problem as T:L has one awesome soundtrack.
