Kacey Musgraves’ rendition of “I Want A Hippopotamus for Christmas” removes the absurdly dull vocals of the song’s original singer, Gayla Peevey (a classic, still), and it could turn out to be the track. The most kid-friendly Christmas song on the planet. The lyrics are goofy, the melody simple, and with Kacey on the track, you know it’s bright. A hippo for Christmas!? Where would it even fit in the house?
