Metallica recorded the song "We Did it Again" with Ja Rule for the "Biker Boyz Soundtrack." The official "Biker Boyz" site states that the soundtrack features tracks that match the high energy pace of the film. The movie is an action-packed contemporary Western on wheels with desperados who live every day on the edge. Lawyers and city workers by day, they take to the streets in their leathers to race by night.
