You guys need to wake up! Mariah is not a performer anymore. I was just talkin to some friends and we all agree and wonder how she went from being a powerhouse performer to what she is now (mtv unlpugged, award shows, even shows like gma). She lip sings the whole part that u heard out of sync and then comes in with the "camera" part. and she has a few "pre-recorded" adlibs at the end. Have u all not seen the HILLS performance??? Proof that she has lost her performance swag. You also can tell when she's lip syncing because she moves around the stage and has more energy. When she's really singing she stands still like she's in a box. She did this the whole last album, lip-syncing the bug endings on songs like we belong together and fly like a bird. Say what u want but u will only be in disbelief and fooling yourselves. She will always make good music and sell a lot of records, but ever since that breakdown she hasn't been a good performer. I think it has given her some kind of anxiety and I hope she gets over it. Because when you are an established powerhouse, you do not need sub-par performances like this, and from what I've seen, that's all she has been giving these last two eras. The last album rocked tho!
