Based on my fave songs i would have to say Stripped, i mean Beautiful is like one of the best ballads ever and i love Can't hold me down and Fighter and i love me some Dirrty, lol but looking at the best album as a whole, Blackout. I feel soooo mad that Blackout is one of Britney's best albums and is so underrated.
...Blackout was so messy :-/ (although I do like some songs of it)
