If you think about R&B artists since 2001, who comes to mind? Likely those who stuck around from the 90s, like Boyz II Men or Mariah Carey. As for any who started their careers post 2002, few really stand out. Possibly Alicia Keys, Pharrell, Rihanna. Perhaps Drake and Trey Songz will join that list. What did these artists have in common? They broke the mould.
