A-HA! It looks like this case is all but closed.
From Goldfrapp.free.fr, here is the tracklisting of the new album, Head First:
5. Shiny and warm
6. I wanna life
7. Head First
Eh? Eh? Methinks we’ve reached the answer! I agree that the woman in the video looks a lot like Christina. Don’t forget, it’s still possible–Goldfrapp did work with her after all!
EDIT: Loads of people think the Twitter’s just a fake trying to jump on for the ride. (More specifically, a PopJustice forum poster who created the account today, though this has still been unconfirmed.)
EDIT 2: It’s definitely fake. And the saga continues…
Can you tell I live for viral campaigns?
