Few artists love Christmas music more than pop superstar Kelly Clarkson. Not only has the onetime American Idol champ performed festive holiday duets with Ariana Grande, John Legend, and Brett Eldredge—her jaunty collaboration with the latter on “Under The Mistletoe” truly captures the season’s romantic mood—but she’s also released multiple Christmas albums. These allow her to add sparkling originals to the holiday canon (the soulful, girl-group-inspired “Underneath the Tree”) and put her own spin on classic standards: A solemn take on “Have Yourself a Merry Little Christmas” becomes a showstopper as Clarkson leaps into her upper vocal range.
