Yo SoF, KoS ain't the only Aphex T fan round here. Personally I'd go for Come to Daddy, just because the video is just a little better than Windowlicker.
Nice list BUT, I'd disagree in a few areas. That Prodigy song is no way the best, gotta be Voodoo People surely? Saying Teen Spirit is Nirvana's best song is asking for trouble fro someone like me (a HUGE, and I mean HUGE, as KoS can testify, Nirvana fan).
Also, I'd of inserted Beck somewhere in there, probably Devil's Haircut, as well as Primal Scream, Trail of Dead's 'Mistakes and Regrets', ummmmm, Beastie Boys 'Intergalactic' and NIN's 'Closer'.
Nice topic though SoF, always gonna cause contention.
