I think he was more of a ridiculed meme than a musical pioneer, at least from what I've seen
He was never really the kind of taking himself seriously but like he wasn't a meme peoples genuinely liked this weird style before . He just set the wave for all those Clowns SoundCloud rappers who try to be eccentric and shit with face tattoos but it's just hot trash.
Peoples will say playboy carti or lil uzi but i remember at that time they were rapping normally its him who started this eccentric style
