Blue Magic (song)

"Blue Magic" is the first single from Jay-Z's tenth album, American Gangster. The song was released as a single on September 20, 2007. In the chorus, Pharrell sings an interpretation of "Hold On" by the R&B girl group En Vogue, who are also featured in the song. The name "Blue Magic" is a reference to a potent form of heroin sold by Frank Lucas at the height of his drug trade in Harlem, New York. An official remix features Pharrell and Trey Songz.
