[Iceman]

“Numb” is very different from your previous collaboration with Eminem. How did this one come about?
The moment I worked with him on “Love the Way You Lie,” I wanted to work with him again, and we did “Love the Way You Lie Part 2.” And then I wanted to work with him again. [Laughs.] I just love working with Eminem. He’s just one of my favorite rappers, and his lyrics—he’s a true poet, and I enjoy that about him. For this song, I needed someone with not only his skill, but his personality. And I needed someone who really understands the perspective and the metaphor in the song of going numb and being numb to everything around and to say, “**** you.” Eminem is definitely the perfect guy for that.
