Carrie Underwood's new Sunday Night Football theme song, "Game On," and opening video debuted on Sunday night (Sept. 9), as the Chicago Bears played the Green Bay Packers. Readers can press play above to watch.

"Game on / Hey, it's Sunday night / Game on / Hey, turn up the lights," Underwood sings in the chorus of "Game On." "America's game on NBC / The only place to be / Game on / Game on / It's Sunday night ..."

Underwood co-wrote "Game On" with Chris DeStefano and Brett James. The trio, plus rapper Ludacris, co-wrote "The Champion," used during Super Bowl LII and 2018 Winter Olympics coverage; together with Priscilla Renea, they also wrote "Oh, Sunday Night," the previous SNF theme song.

"We just felt like it was time to maybe switch it up," Underwood explains, adding that the three penned the "great hype song" specifically for Sunday Night Football. DeStefano and Mark Bright co-produced "Game On," while Tripp Dixon directed the SNF opening video for the 2018-2019 season.

"Carrie brought us [the] new song, and it kind of inspired us to get out of the soundstage," Dixon notes. "Any time you work with a big star like Carrie and combine it with NFL's best, you know it's going to be big, and you know it's going to be fun."

The 2018-2019 NFL season is Underwood's sixth singing the Sunday Night Football opening theme, since she took over for Faith Hill in 2013. Underwood is currently preparing for the release of her next album, Cry Pretty; the project is due out on Sept. 14.
