Just to test, I loaded this in a Parallel common event just to see what would happen. No music played at all, and the game crashed after about half a minute. Yeah, I can't say I'm surprised. What surprises me most was that you said it played from the beginning - at all!
When I changed it to a "None" common event, no more crashing, but yeah, desynching. Like I said, you must give the track time to load. If I space out the loading and playing, I get no desynch issues.
