22. Robbie Robertson (73)
Robertson may have put his solo tours on hold, but he does serve as a music supervisor to Martin Scorsese working on classic films like “Raging Bulls” and new movies like “The Wolf of Wall Street.” After releasing his last album, How to Become Clairvoyant in 2011, the rock star went on to retire from performing live in front of the audience. In fact, he kind of decided to stop touring after his band broke up, but he’s still cranking out amazing soundtracks that audiences can hear in theaters around the world.
