Michael Jackson. You couldn't really say for sure if he did or didn't do it. My main thing is, his music never seemed to propagate those accusations. The message behind said music was fairly utopian.
The talent too, MJ was rare because he was promoted equally to his level of potential from childhood up through young adulthood, where he took off and honed his own craft in real time, with hit after hit, music video after music video.
He broke all time records before he was even 30, completely conquered the music industry like it was easy. His album sales are insane. In a day and age where streaming has displaced physical format sales, even his records after Thriller put to shame modern day acts. This is a testament to his enduring popularity.
Now if you think he did it, and I myself have gone back and forth on this, see it this way: He paid the ultimate price. He was ridiculed, his finances were exhausted and he was looking like one of the zombie background dancers in the Thriller video. And then he died fairly prematurely. He wasn't able to see his actual children grow up. So if you think he was a paedophile, it would appear that the scales of justice had their karmic day(s) with Jackson. What more do you want?
Those last 15 years, the Howard Hughes craziness with his ill conceived Neverland Ranch, his midlife (late life) crisis, I think most people want to forget. When he did pass away it was the cue for the public to nostalgically recall all the years they listened or danced to his works, not the eventually horrific metamorphosis he under went paired with the obvious drug addiction.
To me, that's a natural thing and I won't knock others for trying to extract the good from the bad...no pun intended.
