Eminem is meh, his music is too shallow and not very enjoyable in general IMO.
Try Jurassic 5, Gang Starr, Jedi Mind Tricks or Large Professor if you want to hear some proper hip hop with head-bobbing beats and witty/smooth lyrics.
EDIT: I should probably explain myself better. Eminem's general jist in many of his tracks seems to be either "look at me I'm white, blonde I rap and I don't give a fuck about anything. I'm so randum and qvurki lel" or "my life is shit I hate my life fuck everything" so once you've heard 2/3 of his songs, you've basically heard them all. His lyrics in general are rather simple and the beats are very pop-sounding. His tracks are what I refer to as "chewing gum rap" because it's like a piece of chewing gum. You just chew it for a little while and spit it out because it loses its flavour/you get bored.
I used to be a fan of Eminem myself and I'll be the first to concede that he's made some good music in the past, but he's way past his prime and should start his long overdue retirement instead of grasping at straws for another 30 seconds in the limelight.
TL;DR - Go home dude, you're old.
