Carrie Underwood has been singing NFL themes since 2013. Her third and latest Sunday Night Football theme, "Game On", has been named in a lawsuit filed Wednesday.

The case is Merrill et al v. Underwood et al, U.S. District Court, Southern District of New York, No. 19-05722 states that the National Football League and NBC  allegedly copied the “Game On” theme song used in 2018 for “Sunday Night Football” from an identically-titled song recorded two years earlier.

Heidi Merrill, who said she uploaded her “Game On” to Google’s YouTube in March 2017, said her copyright was infringed after Underwood’s producer Mark Bright rejected her August 2017 pitch at a conference in Nashville to use the song for “Sunday Night Football.”

NBC and Carrie Underwood have yet to comment.

You be the judge.
