i found this out by accident if you add music to your xbox hdd, while playing the game if you change radio channel (using the black button) you get the radio channels listing if you keep pressing it you get an option called TAPE 1 this plays .the music you have installed on your xbox if you keep hold of the black button and press up on the d-pad (not the stick) this changes the track
hope this help
