... Baby One More Time
Oops!... I Did it Again

Circus is underrated in my opinion. I think that it has the perfect balance of uptempo and personal tracks, while still sounding cohesive. I also just love the whole theme of the album.

I agree with this. I haven't listened to Femme Fatale and Britney Jean. My decision is based on the albums I have listened to.

you're not missing out (in my opinion)
