It's actually good music. The visual parts match the music pretty well, too (though it makes me anxious if I look at it longer than 3 seconds).

I do wonder, though, whether it's just over-fits, and takes the original music with some minor tweaks.

Another interesting point would be to know if this music could be sold cheaply without legal troubles (or even distributed royalty free). Most of the music I heard is pretty neat, I could image using them in YouTube videos, or as podcast jingles.
