Query: Yoga Zone CD's

I heard from my Yoga instructor that these CD's were great and they are. In the four set series, I've used the relaxation CD and unfortunately, it did stall for about a minute. That is why I didn't give it five stars. If the supplier would like to send me just that one (I think there were four in the set) that would be great.
