Best Known For: “Diamond Girl,” “How It Was Supposed to Be,” Cassie’s “Me & U”
Why He’s Dope: R. Les is an accomplished Harvard scholar (perfect score on the SATs), producer/vocalist/songwriter who’s well versed in creating hits. The crooner helped pen and produce Cassie’s entire debut album, and his work on her semi-erotic breakout “Me & U” pushed the single to No. 3 on the Billboard Hot 100. Even when Ryan doesn’t use words, his songs speak magic (see: “Gibberish”).
