Tim McGraw's upcoming album is titled 'Top of the World'. He debuted the song by playing a small part of it to the astronauts on the International Space Station.

Taste of Country staff had this to say about the song:

“Top of the World” doesn’t grip one’s heart like some of McGraw’s previous singles have done, but it’s likely not intended to. The new single is a bluejeans-and-T-shirt kind of love song, good for any occasion.

Why Fans Will Love It: “Top of the World” is an easy love song that everyone will find something familiar in.

Key Lyrics: “Don’t know where we’re gonna be / But I know we’re gonna be / Sittin’ on top of the world.”
