Blue Öyster Cult wrote and recorded a song called "Vengeance (The Pact)" for the film, but the producers declined to use the song because the lyrics provided a capsulized summary of the "Taarna" vignette. "Veteran of the Psychic Wars" was used instead. Both songs can be found on Blue Öyster Cult's album "Fire of Unknown Origin". Though used in the film, the songs "Through Being Cool" by Devo and "E5150" by Black Sabbath were not included in the released soundtrack album. These songs are on "New Traditionalists" and "Mob Rules", respectively.
