From a leak on the ILM forums: Britney Spears and DFA.
The demo's rough, with Brit doin' some "la la love you" stuff over the crunchy DFA beat #5. Still, even as an artifact, it's pretty interesting. Give it a listen (it'll be gone in a flash, I'd imagine).
The word from the record company? "Too hip" in a rueful voice. The word from DFA? Brit didn't bring a thing to the sessions, and they usually work by listening to music with the artists they're producing. Spears knew nothing of the bands they were into, and didn't offer anything herself, so it's unlikely that this will get an official release or that DFA will do more work with her.
