I think rappers are better business people than rock musicians. Maybe because their focus is on those benjamins. Nas has a stake in Coinbase, if he holds onto it he could be a billionaire in a few years. Kanye, Dre and Jay-Z are already billionaires. Every member of Metallica should be a billionaire by now, but they were too worried about copyright lawsuits and whatever stupid ideas were in that documentary, singing about being insane er whatever, I don't know I never got to the end of it.
