I just rewatched the interview you posted. What I did not notice was right at the beginning, Eminem hands Sway a copy of an EP that Sway must have done when he was a kid, and asks Sway to sign. This seems an immediate attempt to establish harmony, and Sway is taken aback by the thoughtfulness of the gesture. This does suggest Fe! Its conceivable that Eminem is a very antisocial INFJ, type 4, SX/SP. I am a similar type, and I have had comments remarking on our similarities, especially with regards to my intense stare (which reflects my desire to understand others, not to dominate them). So I can see it!
On the other hand that act may be consistent with an INTJ who particularly values Sway for his contributions to urban music, a demonstrarion of Fi. Indeed Sway's response is one of mild surprise, like 'where did that come from?' Also the personal nature of the gesture suggests Fi rather than Fe, which is a more general radiation of warmth. And Eminem's general happiness to offend others and cause chaos through his music, even with regards to close family members, doesnt suggest Fe. He does express hostility in some songs, but other times he just mocks, and it often seems more for effect.
My instincts still tell me INTJ. He lacks the intrinsic softness, both in voice and in facial features, of an INFJ. But I can see where youre coming from!
