Bigjoe, and the other half of the enjoyment comes from what? BTW, I feel that "the rig" and "the music" are actually independent of each other. One is not necessary for the other, but whether listening to the rig or the music, one cannot do that at the same time as doing other tasks. The music, however, can be used as background sounds, but I don't see (hear?) how a rig can be used as background, except, maybe if white noise is being used.
