Eminem fell off because of his blind loyalty to Interscope records & Dr dre.He could still put out a great album if he changed the direction that he's going in.
"medicine man","Don't front" etc proves that he still has the talent and skill.What he needs is better production,a change in content and too get on tracks with rappers like .P.Monch,Nas,Andre 3000,Lupe Fiasco,Kendrick,Elzhi,and common.And I don't mean records where he is trying to out rap them,i'm taking about records with social & political content,dope beats and great hooks that will elevate hip hop.He also needs to cut down on the screaming,unnecessary fast rapping and over cramming of words.Introduce those 3 elements only when it's needed.
And for crying out loud,stop talikng about raping females,the shot value has worn off.Not to mention,you are a 43 year old man with female daughters.
