I especially like the part describing Beat as a "passive rhythm/music game." You're playing pong, and the side effect of that is producing sounds that work in tandem with the background music. I say this is almost more musical than Guitar Hero/Rock Band, where your goal is complete a song. With real music (depending on your personal philosophies), you're playing an instrument, and the sounds you produce can be seen as a side effect of the performance.

I'd be very interested in submitting something to a theories page on the Commander Video site.
