"Kim" was the first song the rapper recorded for the album, shortly after finishing work on "The Slim Shady LP" in late 1998.  Eminem wrote this song, along with "'97 Bonnie & Clyde" (where Eminem and his daughter go to the lake to dispose of Kim's dead body), at a time when he and Kim were having marital problems and Kim was preventing him from seeing his daughter Hailie.  While the song has been cited as an example of misogyny in hip hop culture, it is often highlighted as one of Eminem's most memorable songs.
