christina é perfeita. Canta e dança tudo perfeitamente

0:51 : walk away from her stripped album. 2:58 : at last, its a live concert. :)

CHRISTINA'S FANS LETS GET TOGETHER AND VOTE HER FOR BEST ARTIST IN HISTORY AT MTV EMAS 2008 !! SHE DESERVES TO BE RECOGNIZED,VOTE AS MUCH AS YOU CAN!! peace ! ;)

Yeah, i think too that Rihanna deserves that spot instead Jessica.

Aguilera is the best singer today, liked that or not. But i dont like her songs so mutch.

Jessica Simpson is a whiny little bitch who "sings" with her nose plugged She can't control her voice as well as Christina can at all

SHE's the BEST!! among the rest!!!! ahmm could anybody tell me the tittle of the song at 0:51 and 2:58?........ well, GO! CHRISTINA AGUILERA!!

Im sry but Jessica shouldn't even be on the list of high notes...its all about the good high note hitters which is Clearly Whitney Houston first & foremost, Christina is next & Mariah is good too but hers can be a tad bit annoying but she's still a great singer!!!!

gay ass jessica ? What a way to use your words buddy .

ahahahah , i just didn't want to name them all. and Jessica simpson has been named on of the best woman in music to hit high notes and maraih carey HAS clearly the best vocals out of all of them you we all know it . Christina comes very close but can't beat maraih .

what about celine dion and whitney housten? and jessica simpson will not be remembered as 'best vocals on a woman' but christina is the best out of all of them

Im sure I saw her waiting on the corner one night outside my appartment someone who dresses the same maybe??

......jessica simpson....? Wtf? I think Rihanna deserves that spot, not gay ass jessica simpson

mariah carey, christina aguilera and jessica simpson will always be remember has the " best vocals on a woman " but clearly mariah carey wins that .

"Contigo En La Distancia"

4:26 tot 4:35

3:54 till 4:08
