In reply to hahaha.

Clearly she has a voice for jazz, which she just displayed. Perhaps u just can't hear too well. Her was great hear. None of those ladies would sang Mariah anywhere. They all have their own thing. Also, that was great vocals. So those saying that it was great are absolutely correcct. You're just angry because your favorite artists can't do it. If you don't have a voice, you wouldn't be able to do what she just did.
