“Yeah” was released in 2004 as the lead single from Usher’s album Confessions. Produced by Lil Jon, the song features Lil Jon and rapper Ludacris and became one of the defining mainstream hits of the crunk era. Its prominent synth line, club-focused production, and repeated hook helped it spread through radio, music television, parties, and dance floors worldwide. The track remains common in nostalgic social videos because its opening sounds are quickly identifiable and its beat gives short edits immediate momentum.
