The song is called "Something In The Water," and it will be featured on her upcoming Greatest Hits: Decade #1 album. She co-wrote it, and it's definitely not like "Before He Cheats". It's actually a faith-based tune.
"It's really kind of a joyous, uplifting song about changing your life for the better and kind of having that 'a-ha' moment, to waking up and your life being different from that moment forward," the singer, 31, explained on NBC's Today.
The country singer tweeted Monday, "Just heard #SomethingInTheWater for the first time on the radio! Yay! So happy happy happy!!!" In typical Carrie fashion, it's already No. 1 on iTunes' country music charts. The full album will hit stores on December 9.
