According to this, Circus > Britney Jean = Femme Fatale, but to me, it's Circus > Femme Fatale > Britney Jean

Circus is pure pop perfection and Femme Fatale is pure electropop perfection. Britney Jean is...pop.

Mess at being piratically Circus in its entirety. Phonography is one of my favorite songs in Brit's whole discography.
