I am very much a bigger fan of Miss Spears ''Grown up'' music, Blackout and beyond, but her older songs are timeless and will be forever enjoyable, this collection gives you exactly that, her ''best of'' her early work, while giving you a glimpse of what's to come with the couple of new tracks. I recommend this over The Singles Collection, cause you really wanna listen to Blackout (and maybe Circus too, depends how your taste is) in it's entirety.

The only missing songs are Anticipating and Breathe On Me, i understand they weren't hits, but easily some of her best songs from back then.
