Who would it be?
As an artist/musician.
As a skilled MC
As a pop icon.
As the media's cockboy
As a figure in music in general.
I realize that in terms of cultural impact, you're all going to say "NO ONE CAN REPLACE EMINEM DA HUR HRUHRURHAERHFADHAFDJHADFIMAFAGGOTASDGHAS" but that's a fucking predictable answer although I agree. But lets pretend that Em disappeared, or even didn't exist in the first place. If you had to choose 1 rapper to take his place, mainstream or underground, as the figure head of hip hop, and their music didn't change at all in the process, who would it be?
This would be the person everyone in your school loves. The one that every 'aspiring rapper' that will never make it is trying to mimic. The person who has been in the news alot, the person who performs and wins big at the Grammies, the person who is dominating radio play and the person who everyone models their fashion by.
I'm aware that Eminem doesn't 'dominate' the radio, isn't always in the news and the other exaggerations but you get my point.
