In the song 'White Privilege 2' Macklemore discusses how he benefits from being a white artist in a black medium.
In his bars, he also mention Caucasians Elvis Presely, Iggy Azalea and Miley Cyrus as benefactors. But he doesn't mention the most famous white rapper: Emimem.
Billboard asked him why, and this is what he said.
Asked if he would include Eminem in the Elvis, Iggy and Miley group, he says yes: “He’s a white person who raps. I think regardless of where you come from or how amazing you are, you’re still a white person appropriating a black art form.In the interview, he also expresses regret that he didn't give his friend Azalea a heads up before he referenced her in 'White Privilege II'.
What do you think of Macklemore saying Eminem is appropriating a black art form? Judging from some of his own lyrics, Eminem may well agree.
