How is this them dissing each other? Sounds to me like they're talking to journalists or something, nothing in those bars indicates they were dissing each other.
There were some slick bars in their verses, breh. You gotta listen, closely.
Andre: "...my relative in jail, stay engaged to whatever make money, now he married to that cage..."
shyt probably stemmed from Andre passing up on money-making opportunities for the group (tours, appearances, collabos, etc.), which soured their relationship.
Big Boi was about makin' that money, whereas Andre wasn't willing to do just anything for money.
