i don't know why it is, that the singing voice, that is, to me, the greatest singing voice of all time, is also, the singing voice i have heard the most complaints about, concerning HIStory. I've never heard him sound bad. And, the one time i heard his voice dip, during a dance move, on the 30th anniversary concert, somehow...it sounded right. I don't know how else to explain it, but, since Michael's voice was, and always will be 'So Michael', and so, unlike anyone else's...it always sounded right to me, when he performed, and sounds right on all his recordings. The most outstandingly bad, anything ever sounded to me, regarding him, wasn't really him sounding bad...it was an attempted Motown recording, where it sounded like his bosses wanted to trap him into singing badly, because the notes written, were too high for any human being..ordinary, or extraordinary...and it sounded as if they thought he was so great, they were immediately envious, and hoped he had a limit. I never felt this way about singers. There was a time that I thought there were a chosen few of singers that couldn't mess up..and it made me wonder if i was ever capable of being as objective as possible for a person with an opinion..but then i heard Stevie Wonder mess up. He was one of the ones i regarded as the chosen few. That's when i realized i was as objective as it is possible to be for a human being, with an opinion. And of course, human beings all have opinions, which limits objectivity to some extent. I've heard opera singers mess up..and, before that, i didn't think they could mess up.
