In fact, the three artists in the running for the 2015 Super Bowl are being asked to pay the NFL for the right to perform their music during what is usually the biggest TV broadcast of the year, much like the high-profile (and expensive) commercials that often generate as much interest as the game itself (the 2014 Super Bowl earned 111.5 million viewers in the U.S. alone).

The Wall Street Journal is reporting that the considered acts for this season's Super Bowl are being asked "if they would be willing to contribute a portion of their post-Super Bowl tour income to the league, or if they would make some other type of financial contribution, in exchange for the halftime gig."
