How the hell would they pull it off though? They've both lost their voices It better be a ballad in comfortable range if so.
Mariah hasn't lost her voice. Of course it isn't as good as it once was, but she's still an incredibly amazing vocalist and even on her worst day she's better than most of the pop girls.
While Alicia to me is and always have been a good singer too. Both of them are true singer-songwriters and that is what I love.
Her vocals were good but she ****ed up some acoustic details. She probably sang like she was in the studio, not in front of so many people in such a big area and with a microphone and moving. That's why it sounded like a screeming sometimes. The echos did not help at all.
