To me it sounds as if the reason for the music not sounding like total crap is, that the author uses pentatonic scales, which are also used in improvisations. (http://en.wikipedia.org/wiki/Pentatonic_scale)

I agree, I noticed that almost immediately. Also, the rhythms are quantized and the tempo is fixed.

It's still a very cool demo, though.
