Pretty freaking sweet. At first I was turned off because I paused Arch Enemy to listen to it, and let me say quite a genre change lol. The overall idea of the song was really sweet. I'd turn down the vocals a little bit (just a touch). The beat-boxing part would IMO be a lot cooler if you didn't repeat "Break!" (I'm assuming that's what it was), and did sort of a beat-boxing solo, and less a chant.
