Wayne. No Wayne = no Drake, no obsession with lean and pills, Wayne was mumble rapping in freestyles because was so high then nikkas started mumble rapping on purpose, Wayne introduced rapping (not singing) with autotune, Wayne made tight clothes mainstream, Wayne brought dreads back to Hip Hop after people were doing braids for years...
He honestly set a lot of trends or popularized things that weren’t the fashion before he did it.
