The Taylor Swift Holiday Collection balances Swift's pop and country roots quite well - she contributes two originals - "Christmases When You Were Mine" and "Christmas Must Be Something More" - to a collection that features the classics "Santa Baby," "Silent Night," "White Christmas," and Wham!'s modern-day standard "Last Christmas," giving them all crisp, cheerful arrangements that are suitably seasonal but also faithful to her bright country-pop.
