Besides that but Mariah doesn't really dance much during her live performances that I've ever seen. She's not like Beyonce.
Then she should stop drinking, stuffing her fat ass, show up to rehearsal, learn the material, and put on a GD show if that is what she is paid to do.
Otherwise, she should not be supported by any fans and should go the same way as Milli Vanilli, a two bit clown whore hack.
That ought to strip her of her grammies as well.
If she is this dishonest, and she doesn't have enough shame to be humble about it or apologize for it, who is to say what filters, buffers and auto-tune shit the original recordings went through.
If you don't sing, don't write, can't dance. . . you are just a talentless hack.
