"Yeah!" is a song by American singer Usher. The song is co-written by Sean Garrett, Patrick J. Que Smith, Robert McDowell, LRoc, Ludacris, and Lil Jon, with the latter two as the featured artists for the song, and with Lil Jon also producing the song as well as incorporating 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.
