I watched this thing about the making of Marshall Mathers LP, it was bout how some of the songs came about, and how Em was feeling at the time. When Dre and Em thought the album was finished, Jimmy said a pop first single was missing. And they started talking about "a formula for a hit". Jimmy said he wanted the same type/formula of song as "My Name Is". "The real slim Shady" followed that route, as did "Without Me" and "Just Lose It".
Jimmy believes in a formula for a good album that obviously involves contraversy. Music is an art,not a Science.
