Well, it's now being alleged that name of the song, as well as the music itself, were both stolen. Fellow singer Heidi Merrill is suing Underwood for straight-up jacking it. And to be fair, her pre-existing version does sound similar to the SNF tune:
For reference, here's NBC's Underwood edition:
In her lawsuit, Merrill mentions that she met with Carrie Underwood's producer, Mike Bright, in Nashville back in August 2017 and asked if a new song was being created for the SNF open for the 2018 NFL season.
Merrill did submit a song but they ended up passing on using the tune "Game On." Well, something must have changed because the theme song that was used for Sunday Night Football sounds eerily similar to Merrill's song she posted on YouTube back in March 2017.
The amount of money she's looking for in return is unknown at this time, but Merrill is understood to be suing suing Underwood, Bright, NBC, the NFL at the very least for copyright infringement.
Too bad she and a host of people are getting sued for a song that was widely hated by the public.
