Wrong. Jackson held writing credits (solo or cowrote) on many of his songs. And, yes, he would beatbox the main line on some tracks, literally making his voice an instrument. Are you really going to sit behind your little keyboard and try to convince us that Jackson was just your average talented dancer/performer with a unique voice caught in a perfect storm? Stop making a fool of yourself.
So few know just how little is required to earn a co-write tag. If you say, I think the line should be,
Hold on, baby, and not, Stay calm, baby, that's a co-write.
Does anyone really think Bieber, Swift, etc. are the engines producing their material?
As with Mutt Lange/Shania Twain, etc., Mikey owes a lot to folks like Quincy Jones, etc.
Jackson was a talented guy with ideas. Like a great many. A catalyst within a scene/era who exploited all the angles.
Jackson was talented and a great entertainer, but to suggest he was on par, musically, with so many other monsters is to expose a hugely limited awareness of what's out there. Or of the art of music, specifically.
Bieber's worth a few hundred million dollars.
He's no more "talented" than the next thousand kids on YouTube clamouring for a piece of the pie.
Very, VERY rarely does the elite in music reach the superstardom heights of the likes of Britney Spears, Madonna, etc.
The general populace eats what's fed to them. They only float on the surface of an ocean thousands of miles in every direction and dozens of miles deep.
