It's not so much that Eminem changed himself in the MMLP2, but after thorough evaluation, I feel that the reason Eminem sounds different than he used to is because his life has changed. I always thought that Eminem had to rap more normal. But the album was pretty natural for him. I guess what I wanted was for him to actually become the person he used to be. That's just how it is, that's what people want.
So where does he go from here? Well, it's apparent that he can't rap too much about his life anymore. Because that has been run into the ground. So he needs some slick concepts. And I don't know what about, but Rap God was good. His best concept on MMLP2 was Bad Guy. Bad Guy was his best song, but Rap God was his sickest song. So he needs songs like those.
And he needs to strengthen his accent, need it back to the SSLP days.
