1. Carrie Underwood, "Something in the Water"
Underwood's latest single grabbed the Number One spot on this list with almost three times as many votes as Keith Urban's second-place "Somewhere in My Car." The soaring "Something in the Water" was the perfect choice for the newly recorded lead single on her Greatest Hits: Decade #1 record, because it fuses the Underwood we first met — spiritual lyrics and that dynamite belt — with the Underwood who's become one of country's biggest forces. Set to sophisticated, modern production, the track spans every note of her register and serves as a bookend to a the first leg of her career that began with "Jesus, Take the Wheel," and shows that, after all these years, she's still just as faithful as ever. It's why her fans are true believers too.
