Sir, I was hoping that I could talk to you about the gym?

I've been reading about exercise physiology and there are quite a few published studies on the effectiveness of music on productivity and output when working out. Would it be possible to add some kind of sound system in the gym that had an easy to use interface? I don't want to assume that everyone will like what I choose for a workout playlist, but I think it would make the space more enjoyable if there was some upbeat background noise.
