Nine Inch Nails (partially lost songs from American industrial rock band; 1990s-2010s)
Nine Inch Nails is a popular American industrial rock band founded in 1988 by singer/songwriter/instrumentalist Trent Reznor. Over the course of the band's existence, there have been 'several songs that have yet to be released', either partially or completely.
The Downward Spiral (1994)
The Downward Spiral is a concept album released in 1994, revolving around the nameless protagonist's descent into self-destruction that eventually leads to suicide. When the album was released, two tracks that were intended for the album were left off.
There is little known about the one of the cut tracks, "The Beauty of the Drug", and the only acknowledgement of its existence was in a rare phone interview with Reznor []. Further Down the Spiral, an album consisting of remixes of various Spiral tracks, contains a similarly-titled song called "The Beauty of Being Numb", though it is partially a remix of Spiral's "Mr. Self-Destruct" and partially an original song by musician Richard D. James AKA Aphex Twin.
In a 1995 article [], Reznor said that Spiral's other unreleased track, a song titled "Just Do It", never finished being recorded. It was supposed to be a short track about suicide, with its only lyrics being 'Just do it / No one will care'. Mark 'Flood' Ellis, who co-produced the album with Reznor, told Reznor that he had gone too far with the song and refused to have it included on the album, leaading to its incomplete state.
When Spiral was reissued with bonus material in 2004 for its tenth anniversery, neither "The Beauty of the Drug" nor "Just Do It" were included in the bonus tracks.
The Fragile (1999)
The Fragile is another concept album, this time drawing from Reznor's depression, released in 1999.
For a time, a photo appeared on the band's official website nin.com showing a CD case marked 'the lost fragile tracks'. No track list is shown, however.
An image from The Fragility Tour Book shows two earlier versions of the tracklist, both including three tracks that were not included in the final product: "Rotation", "Anomaly", and "Stained".
In 2017, Nine Inch Nails released a four disc vinyl-exclusive album entitled The Fragile: Deviations 1. It consists entirely of instrumentals from The Fragile, plus a several previously-unreleased songs. Reznor stated that tracks with "(Instrumental)" were intended to have vocals at some point, and that "Those could be finished, a demo or just an outline." The songs from the Fragility tour book were once again not included.
Bleedthrough (Early 2000s)
In the early 2000s, NIN went mostly quiet as Reznor set about getting sober from his drug and alcohol addictions. In 2004, it was announced that Reznor was working on a new full-length album under the title Bleedthrough.
Following the trend of the two previous albums, Bleedthrough would have been a concept album; specifically it would deal with different layers of reality "bleeding" into each other. The album was ultimately scrapped when Reznor decided that was unable to make the story work, and NIN's next album ended up being With Teeth.
It is unknown just how far along Bleedthrough was when it was scrapped, or how much if any material was reworked for With Teeth.
Despite being scrapped, some general concepts spoken of by Reznor show up in a few With Teeth songs, including "Every Day Is Exactly The Same" and "Beside You In Time" having the phrase 'bleeding through'. NIN's 2016-2018 trilogy of releases, Not The Actual Events, Add Violence, and Bad Witch would later revisit the alternate realities concept.
With Teeth (Early 2000s)
In 2005, NIN finally released their fourth full-length studio album, With Teeth. Prior to that, the official website posted a poster in .PDF format that contained titles and lyrics from the album. Upon release, three songs from the poster were not apart of the tracklist: "The Warning", "Message To No One", and "The Life You Didn't Lead". When a fan asked Reznor about these tracks on the site, he mysteriously replied only with a "?" .
During an interview before With Teeth's release, Reznor mentioned a song titled "My Dead Friend" that would also end up left off of With Teeth. Once again, a fan asked him on the official site, though this time he claimed that several unused songs had "found a home on the next record". The following NIN album was Year Zero, but it does not include "My Dead Friend". While it does have a song also called "The Warning", as Year Zero is a dystopian concept album with themes not touched upon in With Teeth, it is unlikely to have much to do with the With Teeth outtake. Fans speculate that it was retooled into "This Isn't The Place" off of NIN's 2017 EP Add Violence, though Reznor claims that it was written for his late friend, musician David Bowie, who died in 2016, long after "My Dead Friend" was first mentioned.
Finally, two other outtakes from With Teeth, "Non-Entity" and "Not So Pretty Now", were played live for the Live: With Teeth 2005 tour. Reznor said that the studio versions might surface one day, which came true when they were released as part of the NINJA 2009 Summer Tour EP from ninja2009.com, a website made to promote the 2009 joint tour of NIN and the band Jane's Addiction. Though the site is long gone, the EP itself can be found through archive.org.
