Carrie Underwood, her producer Mark Bright, the NFL and NBC are being sued by songwriter Heidi Merrill, who claims they ripped off her song “Game On” and used it for the Sunday Night Football theme.

Heidi says she gave the song to Mark at a Nashville event but was later told that it would not be used.

Her copyright infringement suit asks for an unspecified amount of compensation.

Judge for yourself.
