hidden track

A vinyl record may be double-grooved, with the second groove containing the hidden tracks. Examples of double-grooving include Monty Python's 'three-sided' Matching Tie and Handkerchief, Tool's Opiate EP,{{cite web|url=http://toolshed.down.net/faq/faq.html|title=The Tool FAQ|access-date=2007-03-07|url-status=live|archive-url=https://web.archive.org/web/20070304132245/http://toolshed.down.net/faq/faq.html|archive-date=2007-03-04}} and Mr. Bungle's Disco Volante.

With the invention of digital media and compact discs, alternative methods for hiding unlisted tracks were conceived. With a similar aim of concealment, unlisted tracks are sometimes given their own separate index point on digital media. Songs can be placed in the pregap of the first track of certain CD formats, so that the CD must first be cued to the track, and then manually back-scanned. These are often referred to as Track 0{{cite book|last=Katz|first=Bob|title=Mastering Audio: The Art and the Science|first2=Robert A.|last2=Katz|publisher=Focal Press|year=2002|isbn=0-240-80545-3|page=93}} or Hidden Track One Audio (HTOA).{{cite web|title=HTOA - Hidden Track One Audio|url=http://www.daefeatures.co.uk/htoa.php|url-status=dead|archive-url=https://web.archive.org/web/20090905083000/http://www.daefeatures.co.uk/htoa.php|archive-date=2009-09-05}} A CD player will not play these tracks without manual intervention, and some models (including many computer operating systems) are unable to read such content. On Super Furry Animals' Guerrilla, "The Citizens Band" is found in the pre-gap approximately five minutes before the beginning of track one. A glossary of terms used in the song's lyrics is printed on the interior of the cardboard outer sleeve of the CD. This essentially renders them inaccessible without taking the sleeve apart, hiding the glossary in a parallel way to the song itself.

A less concealed method is to place the song at the end of another track, typically the last track on the album, following a period of silence. For example, Nirvana's song "Endless, Nameless" was included as a hidden track in this way on their 1991 CD Nevermind, after 10 minutes of complete silence within the track listed as the final song.{{cite book|last=Cross|first=Charles R.|title=Nevermind|first2=Jim|last2=Berkenstadt|publisher=Music Sales Group|year=2004|isbn=0-8256-7286-4|page=103}}{{cite web|title=Endless, Nameless|url=http://www.livenirvana.com/songguide/body0ff0.html?songid=31|url-status=dead|archive-url=https://web.archive.org/web/20060720155708/http://livenirvana.com/songguide/body0ff0.html?songid=31|archive-date=2006-07-20|access-date=2007-03-08}} Although it was not the first hidden song to use this technique, it gained significant attention.{{cite book|last=Thompson|first=Dave|title=The Music Lover's Guide to Record Collecting|publisher=Backbeat Books|year=2002|isbn=0-87930-713-7|pages=50–51}} Similarly, short tracks of silence can be layered before the hidden track plays. On Lazlo Bane's debut album, 11 Transistor, the eleventh song is followed by 57 silent tracks, each four seconds in duration, with "Prada Wallet" (sometimes referred to as "The Birthday Song") being the 69th track on the album. The total length of silence between the two songs is 3:48.{{cite web|title=11 Transistor - Lazlo Bane|url=http://www.allmusic.com/album/11-transistor-mw0000615852|url-status=live|archive-url=https://web.archive.org/web/20150926185341/http://www.allmusic.com/album/11-transistor-mw0000615852|archive-date=2015-09-26|website=AllMusic}}

It is possible for a track to be playable only through a computer, such as the '15th' track on Marilyn Manson's Mechanical Animals album, which can only be accessed through an Enhanced CD executable.

There are yet-deeper ways a track can be hidden. A "ghost" track can be subtly mixed to play concurrently with other, dominant audio, or heavily distorted in a way which must be undone to be played. For example, on a DVD included with the deluxe and 'ultra-deluxe' editions of Nine Inch Nails' Ghosts I–IV, two hidden bonus tracks ("37 Ghosts" and "38 Ghosts") are included as digital multitrack files, from which the songs may be reconstructed.

• Aaliyah's self-titled album Aaliyah features the hidden song "Messed Up" on track 15. During the stages of the album creation, Aaliyah had no desire to put this song on the album, but after numerous inquiries from different labels and colleagues, she settled on making it a hidden track.{{cite web|title=Rare Gem: Aaliyah 'Messed Up' (early version)|url=http://YouKnowIGotSoul.com/aaliyah-messed-up-early-version|website=YouKnowIGotSoul.com|access-date=19 December 2018|date=16 October 2012}}
• In some rare cases, it is used to avoid legal issues. An example is Ramones' Loco Live American version, which has the song "Carbona Not Glue" hidden after Pet Sematary on track 17. It was originally recorded on their album Leave Home, but the makers of the spot remover Carbona, a registered trademark, objected. Therefore, reference to the song was removed from the album and cover.{{cite web|url=http://kauhajokinyt.fi/~jplaitio/offilive.html#amer|title=LOCO LIVE (American version)|url-status=live|archive-url=https://web.archive.org/web/20081222014827/http://kauhajokinyt.fi/~jplaitio/offilive.html#amer|archive-date=2008-12-22}}
• "Freedom" by Paul McCartney was a hidden track on the original release of Driving Rain. It was later added as a track on the re-release. The track was not meant to be hidden; it was a tribute to 9/11 victims, and McCartney wanted it on the album. The artwork was already finalised, so there was no choice but to make it a hidden track.{{cite web|last1=Wawzenek|first1=Bryan|title=How Paul McCartney began building his next era on 'Driving Rain'|url=http://ultimateclassicrock.com/paul-mccartney-driving-rain/|website=UltimateClassicRock.com|access-date=19 December 2018}}
• "Train in Vain" by The Clash, which appears at the end of London Calling, was left out of the vinyl's track listing simply because it was a last-minute addition to the album, when the sleeves were already printed. It is thus not a real hidden track. It was originally intended as a promotional giveaway for NME. The later CD versions list the track on the sleeve.{{cite web|url=http://www.blender.com/guide/articles.aspx?id=299|title=The Greatest Songs Ever!

• "Weird Al" Yankovic's "Bite Me" from the album Off the Deep End was put on after ten minutes of silence to scare listeners who had forgotten to turn off the CD player.{{cite web|url=https://www.weirdal.com/archives/miscellaneous/ask-al/#0198|title=Midnight Star "Ask Al" Q&As for January/February 1998|date=2001-06-26|access-date=2021-08-28}} It was also a loose parody of "Endless, Nameless" by Nirvana. The cover of Off the Deep End is also a parody of the album containing that track, Nevermind, and its first track is a parody of that album's first track, "Smells Like Teen Spirit".
• The X-Files: The Album features a hidden track at 10 minutes and 13 seconds into the final track. The track consists of series creator Chris Carter explaining the series mythology and meaning behind the alien conspiracy. The hidden track even includes spoilers and minute details about the show's overall plot that had not yet been resolved on the show itself when the album was released. This track was included as both a surprise to devoted fans who would seek out answers in cross-promotional merchandise, and as a mystery to new fans who would need to watch the show more closely to better understand the track.{{cite web|url=http://www.aintitcool.com/node/1060|title=X-Files knowledge|last=staff|url-status=live|archive-url=https://web.archive.org/web/20121005162143/http://www.aintitcool.com/node/1060|archive-date=2012-10-05}}
• Eugene Mirman's album The Absurd Night Club Comedy of Eugene Mirman includes a hidden track making fun of hidden tracks, and telling the listener that they have a very bizarre mission.{{cite web|last=Mirman|first=Eugene|url=https://www.amazon.com/dp/B0002VEU1C|title=Absurd Nightclub Comedy of Eugene Mirman: Eugene Mirman: Music|website=Amazon|access-date=2011-07-27}}
• The Jam's All Mod Cons does not list the song "English Rose" and its lyrics on original vinyl copies because Paul Weller believed the title and song would lose meaning without accompanying music. They have been added to re-releases of the album.
• Skip Spence's "Land of the Sun" was included as a hidden track by producer Bill Bentley to specifically close a tribute album to Spence, More Oar: A Tribute to the Skip Spence Album.{{cite news|first=Margaret |last=Moser|url=http://www.austinchronicle.com/gyrobase/Issue/story?oid=oid:75120 |title=Back Door Man: The Man Behind More Oar, Bill Bentley|work=Austin Chronicle|date=December 17, 1999|archive-url=https://web.archive.org/web/20070412081144/http://www.austinchronicle.com/gyrobase/Issue/story?oid=oid%3A75120|archive-date=April 12, 2007}}
• Oasis' compilation album Time Flies features the single "Sunday Morning Call" as a hidden track. The album was an anthology of all of the band's singles, but principal songwriter Noel Gallagher openly detests the song,{{cite web|url=https://www.youtube.com/watch?v=caB5RoaBvsI|title=Noel Gallagher's Oasis DVD commentary highlights|last=ac2006|date=30 January 2014|access-date=4 May 2018|via=YouTube|url-status=live|archive-url=https://web.archive.org/web/20170223100253/https://www.youtube.com/watch?v=caB5RoaBvsI|archive-date=23 February 2017}} so chose to have it hidden.

Some hidden tracks are historically significant, have become well known and even occasionally received radio airplay and climbed the charts.

• The Beatles' track "Her Majesty" from their 1969 album Abbey Road is considered a hidden track. It was originally a part of the medley on side two of the album, before Paul McCartney requested that it be removed; the engineer who edited it out of the rough mix placed it after the medley to preserve it, and when the Beatles heard it there, they decided to place it there on the album.{{cite book |last= Lewisohn|first= Mark|author-link= Mark Lewisohn|date= 2004|title= The Complete Beatles Recording Sessions|url= |location= London|publisher= EMI/Hamlyn|page= 183|isbn=0-681-03189-1|edition= 2004}} The original pressings of Abbey Road did not list "Her Majesty" on the back cover song title listing, nor the record label; subsequent LP pressings and then CD issues were issued revealing the track. However, two years prior, in 1967, on the UK version of the Sgt. Pepper's Lonely Hearts Club Band album, there was the "inner groove" that appeared after "A Day in the Life" at the end of side two. It was an unexpected, untitled, and un-credited Beatles recording; so this might be deemed a precursor to the hidden track. A potential hidden track on yet another Beatles album is on The Beatles (also known popularly as The White Album) 1968 double album. The hidden track is a snippet of a song called "Can You Take Me Back", serving as an "outro" to "Cry Baby Cry".
• Nirvana put the hidden song "Endless, Nameless" 10 minutes after the last listed track on their 1991 album Nevermind. It was the first prominent hidden track in the CD era and inspired a slew of hidden tracks on albums in the following years. Lead singer Kurt Cobain said he got the idea from when he would make mix tapes for his friends and then add a secret song after a long silent gap at the end, to startle them. Interestingly, some of the initial pressings of the album accidentally omitted the secret track because the person pressing the album thought it was not meant to be there. This was quickly corrected in subsequent pressings after the band let the label know.
• Janet Jackson's track "Whoops Now", a hidden track from her album janet.,{{cite web|last1=Hampp|first1=Andrew|title=Janet Jackson, 'janet.': classic track-by-track review|url=https://www.billboard.com/articles/columns/the-juice/1562833/janet-jackson-janet-classic-track-by-track-review|website=Billboard.com|date=18 May 2013|access-date=19 December 2018}} was released as a single, and reached number nine in UK Singles Charts, and number one in New Zealand Singles Chart.
• Eels' album Daisies of the Galaxy contains a hidden track, "Mr. E's Beautiful Blues", which was released as a single, and received radio airplay, although it was not featured on the sleeve notes.{{cite web|url=http://www.music-critic.com/rock/eels_daisiesofgalaxy.htm|title=The Most Beautiful of Freaks|access-date=8 January 2009|first=Peter|last=Naldrett|website=MusicCritic.com|date=March 2000|url-status=live|archive-url=https://web.archive.org/web/20080820085323/http://www.music-critic.com/rock/eels_daisiesofgalaxy.htm|archive-date=20 August 2008}} The song was, in fact, released as the first single from the album, and peaked at number 11 on the UK Singles Chart.
• Cracker's "Euro-Trash Girl", an original, was one of their biggest radio hits, despite being a hidden track on Kerosene Hat.{{cite web|url=http://www.epinions.com/content_32102190724|title='Kerosene Hat' is hot|access-date=2007-03-07|url-status=dead|archive-url=https://web.archive.org/web/20071017000850/http://www.epinions.com/content_32102190724|archive-date=2007-10-17}}
• "Skin (Sarabeth)" by Rascal Flatts, a hidden track from their 2004 album Feels Like Today, received enough airplay to chart in the Top 40 on the country charts, peaking at number 2 in late 2005. In mid-2005, the album was re-issued, with the song officially listed as a track, coinciding with the song's release as a single.{{cite web|url=http://www.encoremusic.com/piano/1704836.html|access-date=2007-03-07|title=Piano Sheet Music - Rascal Flatts - Skin|url-status=dead|archive-url=https://web.archive.org/web/20070928110014/http://www.encoremusic.com/piano/1704836.html|archive-date=2007-09-28}}
• Of the two hidden tracks on Lauryn Hill's The Miseducation of Lauryn Hill, one of them, the cover of "Can't Take My Eyes Off You" was nominated for a Grammy in 1999 in the category of 'Best Female Pop Vocal Performance'.

• Tally Hall's 2005 album Marvin's Marvelous Mechanical Museum had a hidden track, aptly titled "Hidden in the Sand", that would prove to be the band's most successful song, gaining over 35 million plays on YouTube{{cite web |title=Tally Hall - Hidden in the Sand (Music Video) |url=https://www.youtube.com/watch?v=EOFA9kPQ_uU |website=youtube.com |access-date=December 10, 2022}} and over 280 million on Spotify.{{cite web |last=Becker|first=Sarah|url=https://audiophix.com/posts/revisiting-tally-hall-surprise-hit-01hv3p66bfaa|title=Revisiting Tally Hall's surprise hit "Hidden in the Sand"|website=AudioPhix|language=en|date=April 13, 2024|accessdate=April 16, 2024}}
• Robbie Williams has had hidden tracks on many of his albums. On his first studio album, Life thru a Lens, the standard edition included one hidden track.Bresnark, Robin. "Review: Robbie Williams – Life Thru A Lens, Chrysalis". Melody Maker (4 October 1997): 51. His second album, I've Been Expecting You, includes two.{{Cite web |title=I've Been Expecting You |url=https://robbiewilliams.com/pages/timeline/entry-album-ive-been-expecting-you |access-date=2024-02-28 |website=Robbie Williams |language=en}} By doing this, Williams' regular listeners would have likely expected a hidden track of sorts on the third album, Sing When You're Winning. To play on this, instead of a hidden track appearing on the album, a recording of Williams' saying "No, I'm not doing one on this album" plays after 24 minutes of silence.{{Cite web |title=BBC Staffordshire - Robbie Williams - Sing When You're Winning |url=https://www.bbc.co.uk/stoke/robbie/discography/sing_when_youre_winning.shtml |access-date=2024-02-28 |website=www.bbc.co.uk}}
