On top of Danny Brown, Big Seal, Royce Da 5'9″, Dej Loaf, and Trick Trick--all native Detroit MCs--Eminem has recruited, brace yourselves, Black Milk, Guilty Simpson, Sino, Marv Won, Payroll, Hydro, Big Gov, Boldy James, Kid Vishis, Big Herk, Icewear Vezzo, Detroit Che, and Calicoe, among others.

With these additions the song title takes on a more literal meaning. If you're wondering what it takes to get 18-plus features on a song, the answer in this case is a 16-minute track.
