Just for laughs...
Merry Christmas from the Family by Robert Earl Keen
Fairytale of New York by The Pogues
Christmas Day by The Beach Boys
My all time favorite!
Other than that, I try not to listen to any 
as there's a lot of Christmas tunes I like. If I had to pick 3:
O Holy Night (Robert Goulet's is a classic)
Silent Night
The Christmas Song (Nat King Cole version, of course!
Dolly Parton, Hard Candy Christmas. And then, all of the Charlie Brown Christmas score.
Not sure if it is properly a Christmas song though.
Let me think about the others for a few minutes.
It's very upbeat and closely parallels a real experience I encountered one Christmas season long, long ago.
Just for laughs...
Pretty much sums up the season for some...
Have I used up my quota yet?
This one is truly a classic.
