Britney Spears: B-Sides, Rarities & Bonus Tracks

Britney Spears' deeper cuts flesh out her enigmatic personality and place her malleable voice in surprising contexts. Glitchy production gives the cautionary tale “Mona Lisa” an added layer of grime, sparkling midtempo tracks such as “Heart” and “I'm So Curious” allow her room to emote, and beat-heavy jams like “Before the Goodbye” are the place for her dance-floor maven side to shine.
