No those are awards, recognitions, and record breaking accomplishments. Why even argument about this? If you ask anyone out on the street they would say MJ without hesitation.
I've been gnashing my teeth and trying to keep out of this for ages, but here goes....
Why argue about this? Because you're being a zealot refusing to even consider the possibility that anyone might have a different, and equally valid, opinion to you. It's art, it's personal and each to their own.
I'm on the street, my friends are on the street and nobody I know rates Michael Jackson that highly -but I wouldn't expect a blinkered Michael Jackson fan(atic) to realise that. Along with Elvis fans you live in a bubble where contrary views are unusual, all your friends probably agree with you but they're not the whole world. Personally I believe that because Michael Jackson's personal life and death (like Elvis) were so messy and his end tragic and early that a number of fans (not necessarily you) have elevated him in their minds to some kind of perfect, genius, saint-like figure. The same thing happened with "Princess Diana" and like Michael Jackson and Elvis she was a flawed human being like the rest of us.
Back to a musical argument, I'd say in my opinion (others may differ and they're allowed to, it's art after all) those that are passionate about music (not just one artist or genre) may appreciate and respect Michael Jackson's music but wouldn't elevate him above all others (at best he's on a level with many other equal but different talents*) whilst those that seem to have got hooked on Michael Jackson early don't seem to have developed a wide musical knowledge/appreciation. If I'm being ****** they're people who are not that much into music but have found something easy listening, non-threatening and non-challenging and got very obsessed about it. To be honest, I've never met anyone who's into a wide range of music that was obsessive about Michael Jackson (they may exist I've just never met any).
Finally, don't equate popularity and financial success with quality. I'm sure Harry Potter and Shades of Gray have sold more than Hemmingway, Steinbeck or Orwell but that doesn't make them better literature.
To be fair Michael Jackson probably is the "King of Pop" but, to me, that's like saying someones the "King of vanilla things", great if you like vanilla things but not so if your tastes are a little more complex.
* personally there's many I'd rate above him
