Michael Jackson

Growing up I never really paid too much attention to Michael Jackson. I know he was the "best" pop artist, or at least according to many people. Aside from his music, he did have a lot going for him, good and bad. I do not know very much about him outside of his music besides all the rumors about how he did inappropriate things. As an African American he seemed to have things pretty good, at least from what I know. My question is why did he change his skin color? I would assume there is more to it than he just did not want to be black.
