This is just my theory, but is Eminem trying to do with this album what he didn't do with MMLP2? Or is he unaware that he's going down the same path?
-The lead single is him rapping over an 80s rock song
-There's a lot of nostalgia involved ("Houdini" is paying homage to "Without Me," he dyed his hair blonde again to promote MMLP2)
-Allusions to this being his last album (Slim Shady dying means Eminem is essentially killing himself, he implies on "Bad Guy" that it's the last album)
-Him reflecting on his past and how much things have changed since his prime
MMLP2 didn't feel anything like the first one, and it was really just a reflection of where Eminem was in 2013. He could have called it anything else, but there's a lot of hype when it comes to making people think it's a sequel. This album could be trying to pay homage to Eminem's old sound and remind people of what his music used to feel like. MMLP2 didn't do that. But there's no way to know for sure until we hear more tracks or know the features/producers.
