"It was quite hard for the band to shift from having played to loops of other people to playing to loops of themselves. We felt it was essential to do that, though, because you can get very lazy with samples. They're an easy way to get the ball rolling, but you're always in danger of sounding like some basic samples with the band on top. You're in danger of being dictated to by what's there, rather than saying: 'this is just our springboard'."
- Pop-producer Flood, on the use of samples on Pop
While the band and crew were working on the Joshua Tree album's mixing, Lillywhite's wife, singer Kirsty MacColl, volunteered to set the running order for the album. The band told her to put "Where the Streets Have No Name" first and "Mothers of the Disappeared" last, with the rest sequenced according to her preference.
