Seasonal Songs - are they always rubbish?

After hearing Mariah cunting Carey on the radio for the millionth tme today I was wondering if there are any good Christmas songs. I quite like the Phil Spector Christmas album I suppose, but I wouldn't really put it on by choice in my own home.

I did think of 2 songs I like, both of which are only reallyseasonal in that they mention snow, and weirdly both of which are album track cover versions where I've never heard the original:
Death Vessel - Snow Don't Fall (not sure who did the original, but I'm sure I read it was a cover)
Galaxie 500 - Listen the Snow is Falling (Yoko Ono originally I think)

Any other suggestions?
