Carrie Underwood Debuts New Sunday Night Football Theme Song

Carrie Underwood debuted the full version of her theme song for Sunday Night Football over the weekend. Underwood took over the singing duties for "Waiting All Day for Sunday Night," which Faith Hill had held down for the past six years.

"I've got this funny feeling that I'm going to be waiting all day for something...," Underwood posted to Twitter, later adding, "Who's ready for @SNFonNBC? Woo hoooo!!! I'm so excited!"

The Underwood rendition of "Waiting All Day for Sunday Night" introduced the week one match between the Dallas Cowboys and the New York Giants, which the Boys won.

"We all definitely wanted to make an intentional shift in the sound and the look and the feel of it," Underwood told the L.A. Times. "Because Faith put such a stamp on it. She made it her own. We wanted people to know it was someone else; it was me - my music, my sound, my voice, my look."
