In reply to Ivy's last sentence...
"Most of the time the simplest answer is the right one":
question: Why doesn't Michael sound like Michael?
answer: because it isn't.
Couldn't resist
unfortunately your question is subjective.
very easily the opposite question can be asked and an opposite answer can be given.
for example
question : why does 2 experts, multiple musicians that worked with Michael and a group of fans think it's Michael?
answer: because it is Michael.
to be clear I was talking about theory wise. Let's summarize shall we
Cascio / Sony / Estate (take your pick) decided to fake some songs for some reason risking reputation, fraud lawsuits, financial penalties and even removal from their positions (executors and Malachi from law enforcement).
They went with Malachi.
Malachi is a Michael Jackson soundalike and apparently according to people here he has the most experience and best technique.
Yet he cannot get through a single song , he needs multiple takes and selection of the "most convincing" parts
So he's both has the "most experience" and "best technique" and also has no ability as well. the people going all the trouble for "most convincing" parts, don't consider his "goat vibrato" at all.
Even though Cascio/ Sony/ Estate has Malachi at their disposal and record multiple takes to pick the best of them, they leave obvious errors (such as snort on Breaking News) on the recordings.
Even though they have Malachi at their disposal they do not record in MJ style with MJ soundalike (Jason) laying multiple lead and background vocals.
Even though they have Malachi at their disposal they do not also create other takes - in other words also create their proof - to convince and shut up 3T.
These faking happens with the knowledge of Cascio / Porte / Malachi / all members of Cascio family and they also effectively include Dileo, Friedman and even TMZ to back them up.
Although the work put out is so crappy and incomplete (see above) and so "obvious" for some fans , yet this "crappy and obvious" fake can effectively fools 2 experts, multiple musicians that worked with Michael including Bruce Swedien and fans. Or the alternative Sony is also involved in this and buying these experts and musicians for their silence and/ or support.
Even though all of the above happened there's no single evidence that would hold in court and prove any of the above claims and nothing is done. And Sony / Estate / Cascio is well protected.
and all of these for what? a 2 Million selling album for Sony/ Estate, Eddie keeping recording in his basement, Porte doing audio work from his home and Malachi continuing to be a cop.
honestly now. does that even make sense to you?
or let's go with the simplest route: this is michael not so good recordings and processed / edited to make them releasable.
That's a whole a lot simpler explanation then the above scenario.
