Very similar Artists as far as both rely heavy on emotion and speak on Personal issues in their Lyrics even covering the same Subjects like growing up in broken dysfunctional homes, speak alot on poverty, troubles with drug addiction etc
Both also are similar in that they both do the Singing thing on their Hooks and even when Singing they use a very similar style obviously have very diffrent voices but the style of Singing is again relying on emotion.
Diffrences are that even with all of these similarties DMX remains a Street Rapper when speaking on these same Subjects/Topics and having a similar emotional style to Eminem while Eminem hasn't ever been a Street Rapper because he never lived that lifestyle only grew up around it while DMX actually lived it and reflects it in his Music. So in a nutshell is it fair to say Eminem is basically a DMX with out the Street/Thug element and vice versa DMX is a Thug/Street version of Eminem?
