The Authorship Story
Data Insight
Of the 35 studio tracks with published credits, not one is written by group members alone: a producer's name sits on every single song. Eminem is on 29 of them, but Kuniva is on 26 and Mr. Porter on 25, which is a far flatter split than a group built around one superstar suggests.
