Carrie Underwood's 2015 Super Bowl opening theme song has been revealed just a few days ahead of the big game.

'Waiting All Day for a Super Bowl Fight' -- a special Super Bowl XLIX version of Underwood's 'Waiting All Day for Sunday Night' Sunday Night Football theme song -- has the country songstress belting out lines like "All right, hold on tight, it’s finally here / Super Bowl Sunday's kicking into high gear / The party’s arrived; time to get up and cheer."

As promised, the tune features lyrics specifically mentioning the evening's competitors: "Hey, Jack, it’s a fact, a champ’s getting crowned / The Patriots and Seahawks in the final showdown / The whole world’s a’rocking; time to crank up the sound / The NFL’s best are here to play."

A video, featuring new and different elements from Underwood’s usual SNF opening, such as a special set design, will accompany the song when it's played pre-Super Bowl.

It's a big week for Underwood, who announced her new single, 'Little Toy Guns.' She'll debut its music video Friday (Jan. 30).

Super Bowl XLIX takes place in Glendale, Ariz., on Feb. 1. NBC’s coverage begins at noon ET.
