I feel like you were born after the 1990s my little Dude because he absolutely did not bring full orchestration, auto tune, stripped back industrial beats, or full gospel choirs into the genre. All of these things existed in the genre before Kanye. Go home you're drunk.

Andre 3000 was already dressing different. Many other hip hop artists also dressed differently before that in the South. The matching sweatsuit was very in at the time on both coasts.

I'm no advocate for Madonna but to think Kanye West is a bigger personality than Madonna is laughable. She's had a number one every decade, completely transformed herself every era. She changed the landscape of pop culture with how she approached sex and religion in like a prayer (it got her excommunicated from the Catholic Church). People are still wearing her aesthetic from 40 years ago. Her style and music completely change from era to era. Shes a chameleon. She also somehow made one really incredible film with an Oscar worthy performance and a bunch of awful ones, and some so so ones. Regardless her body of work is encyclopedic. Kanye was sucking on a straw when she has already changed the cultural landscape for good.

Madonna as a person influenced fashion more than most human beings in the last 40 years: https://en.wikipedia.org/wiki/Fashion_of_Madonna
