Changes

This is the original album version. Characteristic of the band's mid-90s industrial rock sound, it opens with an eerie and quiet machine-like sound collage [[samples|sampled]] from the film ''Leviathan'', which transitions into an imitative musical composition. The structure, repetitive in nature, contains three distinct but similar sections, all driven by machine-like percussion loops and undulating rhythm guitar and synthesized bass. The choruses reflect a brighter mood with prominent melodic synthesizers and glimpses of guitar. The three sections are joined by two quiet instrumental breaks, a technique used later on "[[Even Deeper]]." The ascending synth melody from 5:13 to 5:20 seems to be a reference to or an interpolation of "Laura Palmer's Theme" from the television show ''Twin Peaks''. During this same section, there is a looped sample of a woman saying, "Kirk, help?" from the film ''The Texas Chainsaw Massacre''. The "gong" sound that appears midway through the track and after the bridge is also used near the end of "[[Hurt (song)|Hurt]]", but the pitch is changed.

The song has always been performed with the beep melody as an introduction, though sometimes without the machine loop collage. During the second quiet bridge, Reznor often sings "please don't hurt me," followed by a desperate cry. Reznor sometimes alters the final line of the first verse to say "a thousand lovers" instead of "a thousand others." During the [[Self Destruct Touring Cycle|Self Destruct tours]], the band would be bathed in green light and reptilian "scales" would be projected onto them. On the [[Year Zero Warm-Up Tour]], the intro was further extended with a more articulate sound and Reznor whispering over it.
