Fun.'s recent success has certainly been an influence on Andrew's sound. It's very radio friendly, and a shot at a broader audience. Fun. and Andrew came from the same "scene". They're opening doors and making it known theres a market for that type of style these days. The same way Chris Carrabba and Twin Forks went towards a folkier sound, because there was proven success there with Mumford and The Lumineers. Change with the times, and stay relevant.
