Yes I have in fact,comfortably numb :guitar: was one of the song s I requested at a school dance. Besides can you actually compare Pink Floyd to Eminem?:: And besides that Syd Barrett (Shine on you Crazy diamond was a great tribute to him)i dont' think he was crazy in fact I think his lyrics were genius and he was just missunderstood. But that's off topic it's great that Eminem can make fun of some of his other songs and himself.
