He was a massive icon of the western popular culture in general, not just music. Pretty much the embodiment of pop stardom, scandalous celebrity, all that. Not only does everybody know him, because of his private life everyone also has an opinion on him. The strong reaction really isn't a surprise.
And Coxswain, what the hell?
He sucks because he's been doing it since a little kid? A bit like Mozart and the Williams sisters? And what does people listening to obscure artists have to do with anything? No, he really was that fucking good. He wrote his songs himself, was really one of the best singers ever and a fun fact: really a great dancer too, an idol to many professional dancers.
Alright this doesn't concern you personally and you didn't like his music so no personal sorrow. But the people talking about how this really isn't a big deal, "people die every day you know", just don't know or understand what they're talking about.
This topic has too little Michael Jackson music.
Michael around 12 years old, Ain't No SunshineI'm gonna light a fucking candle.
