My favorite Eminem songs are "Lose Yourself" and "Beautiful." They're what I consider the human songs. I like "Mockingbird" and "Toy Soldier" as well (we used to bond over this in the computer lab at North Shore; my friend would swear by "Mockingbird.")
Violence doesn't speak to me and I've always been disturbed by his songs like "Kim," but then he shows his softer, and to my mind, more human side. That's the Eminem I like.
(I also love the songs with the devil voice: "My Darling" and "Deja Vu." Those are powerful.)
