"Top of the World" is the first taste of Tim McGraw's upcoming McGraw Music/Big Machine release, due this fall. The track, produced by McGraw and Byron Gallimore, bows at Country radio and digital retailers today.

On Monday, the song more than lived up to its title when a 15-second video clip was beamed to NASA and the International Space Station via Twitter.

McGraw, who's won three Grammys, 16 ACM Awards, 14 CMA Awards and 10 AMA Awards, among countless other trophies, is currently regaling audiences on his Shotgun Rider Tour. The jaunt includes the first-ever McGraw's On-Stage Experience; the latter initiative brings VIPs and contest winners onstage with the country superstar for a "DJ-style bar" incorporated into the set. Billy Currington and Chase Bryant are the support acts on the trek, which runs through 9/19.
