It's cool
that you recreated such an awesome song, but like what Azoris said, there's...nothing new about it, other than different instrumentation. Nothin' new, nothin' original. However, since you at least went through the effort, and the fact that the song was recreated so well...you got talent. Try expanding it sometime.
You get a 6 for "you have the potential". Don't let me down, now.
