it's GREAT!
but... it turns too repetitive after a short while...
Maybe because of all the times i used to listen to it while playing tetris...
Maybe if you added something of your own... Besides the fast pacing... Something... I dunno, i feel this is not like complete...
let it be a 9/10 for being the theme of the greatest game in history :P (until 1990? xD)
And a... 5/5 so the score won't be lowered :D
