I really hope the EP rumors are true. It's SO much more effective than an actual album. Of course, I have my doubts and I won't jump into conclusions about it actually being true but, if it is true, it'll probably be FF/Britney Jean rejects (which is what I've been reading). It makes sense.
Unbroken is a solid song that was rejected from FF and that should definitely make the EP. And a lot of Britney's unreleased songs end up being great so the quality of it doesn't really concern me. And neither do the sales, really.
Please happen.
