"Sin" is the fourth official Nine Inch Nails release and the final single for the album Pretty Hate Machine. It contains three remixes of "Sin" from Pretty Hate Machine and Nine Inch Nails' first cover song. Even though the front has a stylized graphic that simply says "5in" and it is generally referred to as "Sin" (including on the official NIN website), the spine of the US version refers to the album as "Sin Long, Dub & Short".

A music video was released, using the "(short)" remix of the song, which featured two girls dancing with each other at the beginning, cutting to a black-and-white footage of a woman, naked except for what looks like straps to spelunking gear and a halogen lamp, walking a wrist-bound Trent Reznor with a bag over his head through what looks like an industrial warehouse complex and eventually to strap him into an Aerotrim where he spins him throughout the video. These scenes are intercut with two young gay lovers who eventually fight, a man and woman wearing ritualistic dressings and dancing, as well as visuals of a piercedphallus and clitoris, all reflecting the song's dark, sexual aspects.
The song itself quotes directly from Clive Barker's Books of Blood. "Stale incense, old sweat, and lies ..." (from In The Hills, The Cities)
The video never aired, but an edited version appears on Closure. The original video later became available through TVT's website.
