Changes

This is the original album version. It is characterised by heavy use of loud, layered percussion loops; in fact, the bridge of the song is completely constructed from percussion patterns and synthesized machinery sounds as well as Reznor's distorted voice. Guitars are featured prominently during the verses and choruses, the latter also including synthesized bass. Each verse is punctured by screamed backing vocals. The repetitive buildup at the end of the song eventually gives way to quiet whispers, which segue into "[[Gave Up]]." The end of "[[Heresy]]" also cuts directly to the beginning of this song when they are played back to back.

This remix contains samples from the album version as well as from performance artist Bob Flanagan. Repetitive in nature, it contains very few lyrics, instead focusing on the percussion loops and synthesized bass and leads, similar in sound to "[[Heresy]]."

This remix has only minor changes with cut up vocals on top, and can only be found on the [[Happiness in Slavery (halo)|Happiness In Slavery halopromo]].

This remix was initially found only on the ''[[Happiness in Slavery (halo)|"Happiness In Slavery]]'' " promo, but has recently been posted to [[remix.nin.com]] by Reznor. Short in length, it loops only few elements of the original, incorporating new synthesizer elements and film samples on top.
