facing reality. "Too Long", the album's closer, is a ten-minute-long electro-R&B song. Samples A significant amount of sampling is present on the album. Rather than creating new music using only the samples, Daft Punk worked with them by writing and performing additional parts. The Discovery liner notes specify permitted use of samples for four tracks on the album: Part of George Duke's "I Love You More" is featured in "Digital Love"; Edwin Birdsong's "Cola Bottle Baby" was sampled for "Harder, Better, Faster, Stronger"; The Imperials' song "Can You Imagine" is used for "Crescendolls"; Barry Manilow's "Who's Been Sleeping in My Bed" is credited for "Superheroes". It has been observed that "One More Time" contains a sample of Eddie Johns' song "More Spell on You", despite it being uncredited in the Discovery liner notes. The Los Angeles Times confirmed this following the breakup of Daft Punk and found that Daft Punk does pay royalties for the sample twice a year to the label, GM Musipro.

Bangalter elaborated that the newly recorded elements were implemented in a way that was equivalent to "creating fake samples [...] where people think there are samples from disco records or funk records." Guy-Manuel de Homem-Christo estimated that half of the sampled material on Discovery was played live by the duo, and emphasized that the resulting quality of the music was more important than the ego of who played which instruments. Promotion and release Daft Punk initially planned to release every song on Discovery as a single, according to Orla Lee-Fisher, who was head of marketing for Virgin Records UK at the time, although this plan was eventually shelved. "One More Time" was released in 2000, ahead of the album's release. The album was available on 12 March 2001, with singles of "Aerodynamic", "Digital Love", "Harder, Better, Faster, Stronger", "Something About Us", and "Face to Face" launched afterward. The ideas for the album's music videos formed during the early Discovery recording sessions. The album was originally intended to be accompanied by "a live-action film with each song being a part of the film", according to Todd Edwards. The band decided instead to concentrate on an
