the label wants money so of course they’d want it, 3000 protecting his image above all as the mystery solo artist
It has nothing to do with Andre 3000 protecting his image. Again, when Outkast appeared on Goodie Mob's first album, it was separate songs. I think this was intentional.
Andre 3000 and Big Boi cannot and will not be on songs together unless it is for an OutKast album. Makes perfect sense business wise and in general.
