One of the biggest changes made in "Straight Outta Compton" was the exclusion of one of the group's founding members, Arabian Prince, born Kim Nazel. And while he's not mad about being completely left out of the film, he admitted on Facebook that it does hurt to have history be changed in such a staggering way (via HuffPost).
After the release of the film, Prince shared his story with HuffPost, stating that during the early days of N.W.A., most of the equipment used to produce their music was his. He alleged that he was working as a solo artist before the group was formed. In the film, when Ice Cube was upset over money and his treatment under Jerry Heller (Paul Giamatti), Prince says that he was the one that first brought it up as he felt used. As a result, he quit the group before they released the hit "Straight Outta Compton." Since then, Prince has made his own music, which was sampled in Fergie's 2006 "Fergalicious" and Eminem's 2013 "Rap God."
Prince alleged on "The Goin Way Back Show" that he was cut from the film due to the fact that he sued Ruthless Records after the death of Eazy-E (via AFH). And, as Eazy's wife was a producer on the film, he assumes bad blood was the cause for his exclusion from the story.
