Paul McCartney's billion shows why publishing pays forever

Paul McCartney is now a billionaire, with a fortune above $1.4 billion according to Forbes, making him the world's third-richest musician behind Jay-Z and Taylor Swift. Billboard notes much of that wealth came from his publishing company, MPL Communications, which bought the rights to lasting hits such as Blue Suede Shoes and Christmas standards. The takeaway for indie artists: owning publishing, your own and others', keeps paying long after the tour ends.
