"One in a Million" is a mid-tempo acoustic rock ballad primarily written by W. Axl Rose, with credits also shared among Guns N' Roses bandmates Izzy Stradlin, Slash, Duff McKagan, and Steven Adler. Released on the 1988 album G N' R Lies on Geffen Records and produced by Mike Clink, the song drew from Rose's personal experiences as a teenager arriving in Los Angeles from Indiana, particularly an incident of being hustled at a Greyhound bus station. The composition features a sparse, intimate arrangement of lead acoustic guitar, rhythm guitars, piano, and light percussion, creating a raw, confessional atmosphere. Its straightforward, vocal-driven melody follows a conventional verse-chorus structure that builds emotional intensity through repetition, supported by basic rock chord progressions and an unpolished, demo-like production quality. At approximately six minutes, it is notably longer than most tracks on the EP, allowing its narrative to unfold at a deliberate pace. The song became one of the most controversial entries in the Guns N' Roses catalog due to its use of slurs targeting racial and sexual minorities in its lyrics, which Rose described as a raw expression of his frustrations and limited small-town perspective. Bandmates initially opposed its inclusion on the album, but Rose insisted. The controversy surrounding the song led Guns N' Roses to omit it from the 2018 Locked N' Loaded reissue of Appetite for Destruction. It remains a rarely performed deep cut rather than a concert staple.
