Here is what happened. Your reaction to Breaking News was different to everything else that happened before because of the following circumstamces, which had never applied before :
1- It was a posthumous release based on vocals never meant for release, with heavy post-production work.
2- It featured third-person lyrics right from the beginning, which was unsettling in a MJ song.
3- It originated from mysterious, unprofessional recording sessions among friends.
4- There had been rumours of the vocals being fake before you even heard the song.
Those 4 factors are why your reaction was different. All 4 factors coalesced into a reaction of emotional rejection. Add to this the echo chamber for emotions and outrage provided by the Internet, and here we are. As for why your reaction to all of the other Cascio songs is the same, that's because you can't shake your conviction they're fake now. Basically, at this point, you can only hear Malachi because that's what you expect to hear.
Had KYHU been the first song to stream, this debate would not even exist.
How insulting to people's intelligence. You are making out that we want these songs to be Jason. But we don't, we desperately want them to be Michael. I don't want to think that Michael was stabbed in the back in such a way after his death. I want to be able to look forward to new songs, not worry about whether they will use more of these songs. And as for your points -
"1- It was a posthumous release based on vocals never meant for release, with heavy post-production work."
So were the other 7 songs on Michael. Same goes for Blue Gangster, Do You Know Where Your Children Are, Slave To The Rhythm, Love Never Felt So Good, I am A Loser, Place With No Name. Yet they all sound like Michael. It is only Cascio tracks that sound so wrong.
"2- It featured third-person lyrics right from the beginning, which was unsettling in a MJ song."
So? The other 11 don't, yet they still don't sound like Michael.
"3- It originated from mysterious, unprofessional recording sessions among friends."
WBSS 2008, originates from the same studio, at the same time yet it sounds fine. And as has been said so many times, even in an unprofessional setting, such as on the phone, out and about, in an interview, Michael still sounds like Michael when he sings. And the Cupeta vocal traits such as the vibrato, accent, pronounciation, snorts etc are all there. Whether you think it is him or not, it is a fact that they are in the songs. Likewise, it is a fact that Michael's own trademarks are absent.
"4- There had been rumours of the vocals being fake before you even heard the song."
I, like most fans, was disgusted at the comments from family members that it was fake and totally disregarded them prior to Breaking News. It should also be noted that none of the family members actually mentioned Jason at that time, so it wasn't like the idea was being put into people's heads. I personally didn't even go on the forums on the day it streamed because I didn't want the surprise of the song to be spoiled. Jason Malachi was far from my mind and it had been a long time since I had heard any of his stuff, yet within the first verse of BN, I instantly recognised him. Also, a friend of mine, who does not use any MJ forums, and wasn't even aware of any authenticity controversy from family or fans, texted me straight after she'd heard BN expressing her disappointment that it wasn't Michael. So how was she influenced by anybody? Unfortunately, it is just the same tired old excuses from believers.
And as for saying KYHU would not have had the same reaction, well let me tell you that that was the song that sealed the deal for me. It is so blantantly Cupeta and his awful singing, especially near the end. So don't insult people by saying that we've been influenced by others. We are capable of making our own minds up, based on what we hear or don't hear in the songs, and I for one hear Jason Cupeta. I don't hear Michael at all, except for the pastes. If you want to turn this around, then we could say you were influenced by the statement from the Estate and have long since made your mind up that it is Michael. It's a lot harder to change from that opinion into the uncomfortable territory of the songs being fake, than it is to change from the opposite perspective.
