Producer: Lil Jon
Album: Confessions

At the exact moment Lil Jon became the most in-demand producer in hip-hop (his sound infecting everyone from YoungBloodZ to the Bravehearts) he teamed up with Usher and Ludacris for this club anthem. Usher—pronounced Urr-srrr, according to Ludacris—kicked things off with his crooning, Jon kept the song hyped throughout, and Ludacris sealed the deal in the end. Although we loved Luda's verse, we couldn't help but note the Freudian implications of "I totally have a madonna-whore complex" lines like, “We want a lady in the street but a freak in the bed.” LOLZ.
