Not the best...
I've seen a ton of tetris remix', (Tune's addicting.) This is not the best, but not the worst either. It seems crazy that the intro should be 1/3rd of the song. Maybe over that one minute span, you could increase the speed the more it progresses into the song. Then make a sorta blast ( Dunno music terms) then go all crazy fast. But right when it goes crazy, I'm really blown away with that. 10 because, obviously, IT'S TETRIS!!!
