More on Conde Nast Rapper-producer Jonathan "Lil Jon" Smith is best known for turning everyday words like "yeah" and "okay" into bloodcurdling sonic extravaganzas. He's crafted hits for the likes of Usher and Ludacris; his first solo effort, Crunk Rock, will hit stores on June 8. But given the state of the recording industry, he's focusing more on a concept that doesn't lend itself to his trademark exhortations: diversification. Lil Jon's non-music revenue streams include a line of Oakley sunglasses, an energy drink and a wine label.
