Yeah!" is a song by American recording artist
Usher. It was written by Usher,
Lil Jon,
Sean Garrett,
Patrick J. Que Smith,

crunk and
R&B—which he 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 27, 2004, after Usher was told by
Arista Records, his label at the time, to record more tracks for the album.
