Definitely, it's her second best and her most personal album imo. The only dud is "My Baby", every other track is near flawless and the bonus tracks >>>
It's not amazing, but it's a good pop album, imo. I remember when I was OBSESSED with this and all I would listen to was Circus and Blackout on repeat and that was my life.
Tbh, It was the last PROPER Britney album we had. Everything else from her since has been extremely throwaway.
