The short and simple answer to this question, is that you can use ANY BELLYFIT® MUSIC MIX ON CREW, WITH ANY OF THE CHOREOGRAPHIES. In the credits of the CREW videos, you will see the name of the mix that we used for the filming, but this is just an arbitrary mix that we chose to use that day, some of which are beta (test) mixes and never even get released. So don't get too hung up on the music that is used in the CREW videos. We want you to mix and match the music with the routines and have fun with it.
