Honestly, after reading one of the Michael Jackson
threads on Gearslutz where people who worked with him commented and shared stories,
I highly doubt that all of Michaels success can be attributed to MTV. Sure it helped his success, but from what it sounds like, Michael was incredibly dedicated to his craft and his music meant everything to him. The fact that he would come in the studio with complete horn arrangements in his head is amazing. He did the same thing with string arrangements. I also watched a video of him in a session recording We Are The World...it's like a 10 minute clip and the guy did a bunch of different takes of parts throughout the tune and I think maybe ONCE did he hit a bad note. Good luck finding talent like that in today's world. Whether you like it or not, Michael Jackson was an incredibly talented singer and performer. The guy didn't sell 750 million records for no reason.
And frankly, just because you listen to a wide variety of music doesn't mean that you know what is good, mediocre or bad to anyone but yourself.
