I think "Back To Basics" is the best Christina Aguilera CD so far. People may disagree and choose "Stripped" as the best, but I find I like this CD more and more every time I listen to it. I tended to skip a few tracks on "Stripped" but I don't skip any on this CD. The new sound and style is really great. I also like the little bonus video on CD 2. It's not much, but it's nice.
I love every song but my absolute favourite songs are Makes Me Wanna Pray, Ain't No Other Man, Still Dirrty, I Got Trouble, Hurt, and Save Me From Myself. It's really hard to pick favourites since all of the tracks are so good. Back to Basics is definitely a must-have album.
