Eminem and Cage started around the same time...they used to be cool...they were supposed to blow up together...and when Eminem dropped his demo to Dre and blew up...he didn't bring Cage up with him...therefore causing the beef that we see between them now...and they do sound similar at timez...but there is also a world of difference between them...Eminem raps faster 1st of all...and they have 2 completely different flowz...Eminem mostly has multie'z within' multiez when he rhymez...and Cage just usually rhymez the last coupla wordz...
