The missing word in Pixies’ “Where Is My Mind?” lyric is “mind.” The song’s repeated refrain asks, “Where is my mind?”, giving the track its title and its most recognizable line.
Pixies released the song in 1988 on their debut studio album, Surfer Rosa. Black Francis wrote the lyrics, which combine surreal images with a feeling of disorientation. The song’s distinctive quiet-loud dynamics became one of the defining traits of the alternative rock sound associated with the band.
Many listeners encountered the track through the closing credits of Fight Club, David Fincher’s 1999 film, where it became closely associated with the movie’s unsettling themes. That connection sometimes leads people to mistake it for a song written specifically for the film, but Pixies recorded it more than a decade earlier. The canonical lyric and title both use “mind,” making the stored answer unambiguous.
