Eminem has some insane lyrics no doubt. He's not my favorite but I'll admit he's good. No one mentioned Jedi Mind Tricks, so I'll suggest you should DL a few of their songs, see how you like em.
Just to name a few: I Against I, Muerte, Nada Cambia, Sacrifice, Trinity, The Executioner's Dream. DL some of those, or others that seem to interest you and see how you like em.
