What original Christmas do you like?

I'm not talking about Jingle Bells, Frosty the Snowman, or any of those traditional Christmas songs that has been sung by the 1,000th person, I'm talking about Mariah Carey's "All I Want For Christmas is You" or Band Aid's "Do They Know is Christmas", you know songs that haven't been remade but they're for Christmas. So what songs do you like?
