It's all bullsh*t! :)

1st - There was nothing wrong with her voice. She did it all like she used to do it years ago...

2nd - I guess not all of you here have listened to that, I call it "Hawaian", version of the song. I heard it first on a video of one of her tours some 10 years ago I think. And it sounded exactly the same... Maybe you should try to find it and listen to it to see if there's any difference in her singing it then...

3rd - Mariah just let the other singers do some parts of the song. Though they were not that good and it was a little hard for her to tune in with them... :))

That's all...
