Britney Spears "3" (prod. by Max Martin): Brit goes in on some club-happy shit this go round. I actually mess with Britney when she's not doing the usual - I'm not saying I'm blasting this in my headphones, but I appreciate the steps outside of her box (or whatever box people thing she belongs in) and does something different.
This is taken from her forthcoming singles collection.
Shouts to Team Supreme.
EDIT MITHOOS has just posted some updated tracklists for the collection, including the "Ultimate Fan Box", which features singles b/w their B-sides - lots of remixes!
