I know a lot of people say Relapse was "horrorcore", but to me it wasn't evil. Like, yes he was talking about killing bitches and whatnot, but he seemed more like a mischievious rascal than the spawn of Satan. 3AM, Same Song And Dance, Buffalo Bill, Music Box, and even Stay Wide Awake, while I love them, just don't feel genuinely wicked. My Darling is great horrorcore to me, fighting with the devil and trying to kill himself to get rid of his demons? That's far sicker that any other Relapse track. It's demented when you think about it, really scary shit.
These are my real evil, wicked eminem songs. To me, these are the songs where Em really let's the evil possess him and gets on another level of evil. I feel like he coulda sprouted some horns while recording these.
