'The Essential Britney Spears' is the most complete overview of the "best" of Britney Spears to date!

On the first disc, we get all of Britney's singles starting with 1998's stonking "... Baby One More Time," through 2004's "Outrageous."

The second disc picks up with 2004's "My Prerogative," and runs all the way through last year's "Scream & Shout (feat. will.i.am)."

Where other Britney compilations ran no longer than a single CD, this is a double-disc set with over 30 tracks - more than enough space for all of her hit US singles This double-disc set reveals that she had two strong, distinct phases to her career: the bubblegum pop ingénue of the new millennium, followed by the blackout club diva of ten years later.
