NBC loves country stars!  With Carrie Underwood singing the Sunday Night Football theme on NBC, now Blake Shelton sings the NASCAR on NBC theme!

According to Taste of Country,

"The title track of his most recent album Bringing Back the Sunshine has been chosen as the NASCAR opening theme, and the star will be performing it live this Sunday, July 5, prior to the Coke Zero 400 at Daytona International Speedway."
Very cool!!
