great post. one thing to add: in other genres like rock etc bands have their songs/ideas and get shit produced by dudes like rick rubin. even if he doesnt play any instrument (the band does obviously) but he coordinates, adds ideas and instrument recording sessions and whatever the fuck. kanye does exactly what OP describes and its not better or worse by the way he does it compared to other producers but its great because his results are dope + he gives people credit.
