Mariah Carey's "Merry Christmas" album is just amazing. My favorite track is "All I Want For Christmas Is You" followed by a close second, "Miss You Most (At Christmas Time)." And her version of "Hark The Herald Angels Sing (In Excelsis Deo)" is breathtaking.
"White Christmas" has been a favorite of mine since I was very little.
And in terms of J-Pop, "itsuka no merry christmas" is great! And "shiroi koibitotachi" as sung by Ayu & Chemistry.
