It sounds very similar to 'In the Zone', but I think in general the album is a lot stronger. I love almost all the tracks except Mannequin, Mmm Papi, and Rock me In. I wish the US market would have got Quicksand and Amnesia as bonus tracks; I absolutely love those songs. I guess that just means I will have to go out of my way to try and get them. However, I have to say it's another amazing album from our girl Britney!! I knew she could do it. HAPPY B-DAY BRITNEY!!
