Reason #4: LL gets to enjoy the fruits of his labor by being the Grammys host.
A lot of hip-hop legends don't really get the respect that they deserve once they're past their prime. Sure, they might be honored at, say, the BET Hip-Hop Awards or something like that. But, they don't get a whole lot of validation at this point in their career. By hosting the Grammys, LL is able to keep himself relevant and enjoy his status as one of the greatest rappers to ever pick up a microphone.
