Easily Michael Jackson. He has inspired more people than any other celebrity or person (if you don't count religion into this). Not just that, but he made great music, no one could deny that. No matter all the rumors and tabloids, his music broke barriers. His Album, Thriller, has sold more than any other Album in history. He just didn't make music just so he could have more money, he made well something magical. The music videos he made were more than just promotional crap with some lip-syncing, nice effects, and some back-up dancers, he made a whole story. A mini-movie. Can you name one memorable music video Elvis did? none really. MJ has dozens. His music is still relevant 30 years later, which is VERY impressive since most songs can't last a week until the next "hot" thing comes along. Well that's why I think that he is not only the king of pop, but the king of music.
