"Will 2K" is the second single taken from American rapper Will Smith's second studio album, Willenium. The single was released on September 9, 1999. The song was written by Smith with a selection of other songwriters, and was produced by Robinson, and samples instruments and lyrics from the chorus of The Clash's "Rock the Casbah," as well as bits from "Superrappin'" by Grandmaster Flash and the Furious Five. The single peaked at number two in the United Kingdom and is regarded as a favourite amongst fans. The song pays homage to the new millennium, despite being released nearly two months prior to these celebrations. The song features vocals from Cedric "K-Ci" Hailey of Jodeci/K-Ci & JoJo.
