Like many of us, Carrie Underwood has a hard time singling out a number-one Christmas song, but among her favorites is a song that she finds a heart-warming message in.

“One of my favorites is ‘Little Drummer Boy.’ The sentiment behind it is just so honest. They’re bringing gifts to baby Jesus. He doesn’t have anything. He’s poor, so he says, ‘I know. I’m gonna play my drum for him. That’s what I have.’ And to me, that was a gift that was given to him by God – his love of music, I imagine he was a good little drummer.”

On her Christmas album My Gift, Carrie’s son Isaiah joins her on “The Little Drummer Boy.”
