I think "Do Somethin'" was probably recorded during Britney's sessions with Bloodshy & Avant: "Toxic," "My Prerogative," "I've Just Begun," and "Showdown." I bet "Tell Me What You're Sippin' On" was produced by them too. (?) Just by the title.
I think, though, "My Prerogative" was recorded exclusively for the greatest hits -- they just didn't plan on releasing it until after Britney finished touring. But since it didn't happen, they bumped the release date up by like, a year.
Anyway. I love the song. I'm not going to say it's the best she's ever done (I'll wait for an HQ, please), but I'm really pleased with the direction she's going in for this album. *gets excited 'cause I'm talking about Britney's new album* How exciting! I love the lyrics. It's quite...autobiographical. The "Ladies, does that make you cry? Fellas, you have to say goodbye" is like "Ladies, Kevin's taken. Boo hoo. Fellas, Britney's taken. BOO HOO!" I dunno! The song has like...a way different vibe than a lot of her stuff. The title is quite artsy, and it's quite well written. That's my 2 cents.
