If MJ is king of pop and elvis is king of rock and roll. who is the king of rap?

I think right now it is Tupac. It may be lil Wayne in the future|||Satan himself probably lol|||Must be Tupac, that's what a lot of people think. But many others disagree, and name some guy that no one's ever heard of. If you ask people who the king of Pop is, a majority will say Michael Jackson, and if you ask about the king of rock, a majority will say Elvis, (but it might also be Chuck Berry). And no way is Lil Wayne ever going to be crowned king of rap.. this guy's a f*cking joke! He doesn't even rap in his 'songs', and I don't know why people actually pay to see him.|||Tupac or emenem|||Tupac!!!!!! He will always be The King Of Rap just like MJ will always be the King Of Pop!!!!!!!!!!!|||Biggie|||No way in hell it is lil wayne. Either tupac or eminem cuz they actually rap. Wayne just talks in his f*cked up voice.|||... Did you seriously compare pac and Wayne? Wow.|||Dr. Dre or Tupac. Maybe it's a joint leadership.|||Nas
