Some major Rap and R&B acts have been nominated for the Rock & Roll Hall of Fame. Mariah Carey, OutKast, Billy Idol and other legendary musicians have been nominated for the Rock & Roll Hall of Fame. This is the first time OutKast has been nominated for the coveted spot in the historic institution. Nominees like Mariah Carey are returning nominees who have yet to be inducted. The inductees will be honored at the Rock & Roll Hall of Fame later this year. A date has not been confirmed yet but it will be held this fall in Los Angeles.
