HARDER! Totally. Better..? Impossible. Stronger? Sure, but not really faster. Where exactly does Deadmau5's remix of the Daft Punk classic fall? Ultimately you'll be the judge, but my assessment is that it stands out as a unique track, barely reminscent of the original.
How? Well, the remix features a much more forceful bass-line, while easing off on the dancey house-factor the song became so famous for (that's not to say it doesn't take on an insanely dance-worthy life of its own). Specifically, I think it boils down to the numerous spaced-out interludes featured throughout the song, clear examples of Deadmau5 playing around at what he does best: teasing the audience before dropping a fat beat.
