Noting he's invested in ventures as diverse as restaurants, Wild Shot Mezcal liquor and a record label, as well doing endorsements for Ford, the magazine said he earned more than fellow music moguls Diddy and Jay Z.

Kenny Chesney was No. 3 at $44 million, followed by Jason Aldean with $37 million and Luke Bryan with $34 million.
