I've been on three times, twice in car 3, and once in car 4, and I was much more impressed in car 4. And since I think car 2 spins the same way, that may be nearly as good (though car 4 does have a pretty dang good pop of air towards the beginning).
I didn't get any music at all, just car noises. I suspect it could be related to the fact if you're being held outside the stations for an extended time.
