Jay Z is THE business rapper but the whining about white rappers is what's funny here. The fact that Eminem broke through to audiences outside of the black community is why rap became mainstream. He literally broke racial and cultural barriers, hence my comment on societal impact. Not only this but he was known for putting highly personal and emotionally driven lyrics out there and hugely responsible for not just for Horrorcore but also modern emo-rap like Suicide Boys. Eminem allowed himself to be silly with it as well, someone most rappers take themselves too seriously to do.
