I'm not afraid this'll happen, but just in case you think this breaks some kind of copyright, Trent Rezner put the multi-track files on his website here: http://yearzero.nin.com/ so.... It's cool. Plus his new album is under Creative Commons, just like us! How nice.
So yeah, I did this a while ago. Spliced up the lyrics... turned out O-kay... the ending is the better part though, since I drop the bass and you hear all the random "this is NIN???" sound files. like trumpets!
