Maybe Uzi Vert...Mr "all my friends are dead". That song got so much buzz from the youth AND the old. even oldheads rocked with that whole song and it will probably go down as a classic for this era.
I don't know your age but if you are in your mid 20s like me, i wonder if this new generation will go through the period we went through where most of our legends were dying from like 96 to 2003...from pac, biggie, big pun, aaliyah, left eye, jam master j,etc. I still say wayne will top this if he goes as i expect
as far as cult leader goes you remind me of a youtube comment i read online months ago explaining why this current rap is the new rock and roll from the new stars like XXXTentacion, Uzi Vert,etc, their image and features, demeanor,etc.
i don't know too much about grunge but doesn't this new rap just remind you of that imagery?
