Country Jam 2014 isn't quite over with yet, but there's already huge news for next year's festival. Tim McGraw has been announced as a headliner for Country Jam 2015.

The festival takes place every year in Grand Junction, Colo., bringing together some of country's biggest acts for four days of non-stop music and fun.

This year's festival featured headlining sets from Brantley Gilbert, Lady Antebellum, Eric Church and Jake Owen, and included half a dozen performances from a wide variety of acts each day. Even more fans turned out for this year's Country Jam than last year, drawn to the broad range of talent onstage in one place.

McGraw is sure to up the ante for next year's fans, bringing 35 career No. 1 hits to the country music party. He's been out on the road this year, promoting an upcoming album titled 'Sundown Heaven Town' that is set for release in September. By the time next year's festival rolls around, it's not unlikely that he'll have scored even more No. 1 hits to add to the set.
