Query: Mariah should be embarrased!

They call this a tribute? Hah! It's more of an insult. Who in the *&%# is that singing on the album? Well, whoever it is that person couldn't even sing a Britney Spears song. I am extremely dissapointed. I thought Mariah herself, or other artists, would be singing her songs...not this nobody who can't even sing.
