In addition to two official Greatest Hits, there are many others with some hits from Britney Spears, but in The Essential Britney Spears has full 2 CD's with 32 songs. The first CD starts with .... Baby One More Time, Sometimes, Lucky, Stronger, Boys, Everytime, etc. All extractions from albums Baby One More Time, Oops! I Did It Again, Britney and In the Zone. Unfortunately there is no single "I Love Rock 'n' Roll" and "Anticipating". On the 2nd CD continues with songs from Greatest Hits: My Prerogative, Blackout, Circus, The Singles Collection and Femme Fatale. That's where the firecrackers Scream & Shout it. Thus, this publication has all the hits - except for the Britney Jean era.
Featuring a pleasant surprise but also negative. The negative is that the two CD's are aligned. The positive thing is that there is even a booklet with many photos, a text by Gary Graff and information on individual tracks (publication, Highest).
