The song samples Billy Squier's "The Stroke", as well as the Beastie Boys' "The New Style" and "(You Gotta) Fight for Your Right (To Party!)", both songs taken from their 1986 debut album Licensed to Ill, which Rubin had also produced. The song was heavily downloaded in its first week of release, resulting in the song debuting at number three on the US Billboard Hot 100.
