I can't agree with you there Rukas. EVERY single artist you mentioned there owes a bigger musical debt to Prince than they do to Michael. Every last one.
Sure, they are all trying to look and dance like Michael. But if we're talking about the music, it's Prince through and through. Nobody ever mixed soul and r&b with electronic sounds before Prince, not even Michael. Compare Thriller with 1999 (both released the same year) and then compare Bad with Sign O' The Times (again, released the same year). Prince was always musically light years ahead of Michael, and that's evident in the sounds of today, all the trails point back to Prince, Jimmy Jam & Terry Lewis (who were Prince proteges), and Teddy Riley (who's entire style came from Jam & Lewis, and their style came from Prince). When people like Justin Timberlake are going as far as hiring ex-New Power Generation band members in their quest to sound like Prince....well, that says it all.
Every musician on the planet in the 80's was trying to sound like Prince - even Michael. I read an interview recently where the keyboardist who played on Thriller (the title track) recalled a day when Quincy Jones walked in, handed him a copy of Prince's 1999 album and told him that he wanted the synths to sound like that. Not to mention, "Dirty Diana" is quite blatantly Michael attempt to imitate Prince's "Darling Nikki"........and I can go on.
?uestlove once said that Prince is "your favorite musicians favorite musician" and that's damn true. Hell, most of us are here because of Tupac - and Pac's absolute favorite artist was Prince too - I had long ass conversations with both Johnny J and QD3 about how big of a fan Pac was, since both of them had flipped Prince grooves for Pac songs (Johnny flipped 777-9311 for Whatz Ya Phone #, QD flipped Do Me Baby for 2 Live & Die in LA)
I'm not denying MJ his due props - hell, I was an obsessive MJ fan for a good decade before I was really familiar with Prince's work (I literally watched Moonwalker every single day from the age of 6 to the age of 13......I even went to a MJ fan party once, lmao).
But Prince's musical stamp is all over modern black music - naturally, since he did more to define it than arguably anyone else - the only others on that level are Chuck Berry, James Brown and Stevie Wonder.
MJ didn't define anything musically - he defined what it is to be a global superstar. Sadly, musically he's been mostly following trends for the last 20 years - and by the time he jumps on 'em, they're dated. (HIStory is the exception - that's a fucking beast of an album, except for a few schmaltzy ballads).
MJ's influence is style, hype, image and marketing over actual substance, and always has been.
