This is one of my favorite Mariah songs.. and probably IS one of the hardest to sing. I do think Kelly C. could slay this now. She did it on Idol but was at the point in the competition where her voice was hoarse and strained from the constant singing, but it was still decent. Her voice has matured a THOUSAND times and gotten much richer since Idol so I'd LOVE to hear her do it now. Of course the original is always the one people will remember, but I'm really just saying of all the singers out there I think Kelly would do it the most justice.
