A few others have said this too @ "Bad Guy" ending the album.
Try starting the album with "Evil Twin" and ending with "Bad Guy", it actually works well and I think better; there's something not quite right about ending on "Evil Twin".
I think this actually works better, "Evil Twin" is a nice intro which kind of sums up the themes and what you may be expecting of this album and dismisses it, it also addresses the duality right off the bat which makes much more sense than addressing it after "Headlights".
"Evil Twin" seems to address the duality, flip-it and kick off the musical ride.
And then you go through the ride, wondering if "Stan 2" will ever come, and then right after an emotional climax ("Headlights"), the saga ends with a metaphorical/storytelling pivotal closer. And then you'd walk away with that last 2 minute climax which pretty much perfectly ties-up the themes of MMLP and Eminem's career thus far... seems like it would be as much a genius closer, as an opener.
Thoughts yo?
