Que, Robert McDowell, and LRoc, and is produced by Lil Jon. The song incorporates crunk and R&B—which Lil Jon coined as crunk&B—in the song's production. The song was released as the lead single from Usher's fourth studio album Confessions (2004) on January 10, 2004, after Usher was told by Arista Records, his label at the time, to record more tracks for the album.
