Who is the EP of each album?

[electraheart]

I'm having trouble finding out who all the executive producers of each album are, mostly for the older albums. Does anyone know and can confirm?

BOMT - I'm assuming Eric Foster White
OIDIA - Eric again? Maybe Max Martin?
Britney - ???
ITZ - ???
Blackout - Britney (queen)
Circus - Larry & Teresa LaBarbera Whites
FF - Max Martin & Kesha's ******
BJ - will.i.am in the most egregious crime in pop music
Glory - Karen Kwak

Thank you to anyone who has leads on the first 4!!!
