Isn't a holiday album from the cherubic-voiced, delightfully naughty Glee kids what you always wanted for Christmas? Gifted as they are, the kiddoes deliver. By now, Lea Michele (Rachel) is like fruitcake: a little of that rich voice goes a long way. So it's nice to hear some of the other performers getting more ear time with several group numbers. Amber Riley's Mercedes belts a heavens-reaching "Angels We Have Heard on High," but the sweetest tidings is "Baby It's Cold Outside," a duet between Chris Colfer's Kurt and his new love interest.
