Quincy didnt even think billie jean, a song mj wrote & produced by himself, was good enough for the album. mj had to convince him. and mj wrote & produced 9/11 songs on bad by himself.
qj was no more of a contributor to those albums' success than mj was.
i always notice some of you prince fans downplay mj's creative accumen, by over- inflating quincy's contributions, just to elevate prince.
what kinda insecure bullshyt is that?
Quincy also hated 'Smooth Criminal' and didn't want it on the album. Thankfully MJ knew better.
