Query: Britney rocks!!

I have to say this is my favorite Britney album. She is totally amazing. Though "In The Zone" is not the strongest song on the album it is definitely my favorite. Her duet with Madonna is amazing. The CD showcases her vocal range beautiful and mixes a whole bunch of styles together - from pop to techno to r&b to hip hop. I recommend anyone that likes Britney to have this in their collection!
