No Xtina is not a great vocalist. She's a great studio singer. I do not give the slightest fuck what Rolling Stones said. They put Patti Labelle under them all and put Aretha number 1 and that is incorrect. Patfi over them all. Anyway, Xtina is a flop and a terrible excuse for a live performer. When I used to be a fan, I went to her Back to the Basics tour and nothing but prerecorded tracks and straining. We're talking about Mariah bad days and other bsd days but Xtina has NEVER had a good day. (Looks at failed live Run to You every single one of them). IDK how a Xtina fan can talk about anyone when she only has two successful akbums, one moderately successful era (5 million doesn't compare to the multi platinum plaques seen by Mariah, MJB, Beyoncé, and a bunch of other singers and entertainers... hell Janet saw 3 million after being blac. Listed from the SuperBowl). Her last tthree albums have all flopped barely seeing a million worlwide. Her Greatest Hits even with the aid of a cheap DirecTV commercial failed just like her career. In the Words of MJB, "... Britney may not be able to sing like you, but she will go further than you because she knows how to treat others.... She is just nasty... I'm just putting it out there." XTINA is FLOP.
