Best Christina Aguilera Album?


I prefer her more "bluesy" songs but don't have any of her CDs. Where should I start?
Saw her on the Sandy fundraiser accompanied by piano only. Thought it was great!

My favorite is "Back To Basics". It's more soul/jazz/blues/big band style than any of her other stuff.
Yes, the woman has a voice and knows how to use it, what a talent! I've just never paid much attention but the time has come.
