There are simply so many to choose from, but the kind of music that puts the Christmas spirit in me is a simple carol, any carol, sung by an a cappella boys' choir.
There is nothing more pure and innocent than a boy's soprano voice.
Moving on to instrumental music, one of my faves is stuff done by the Canadian Brass, like these:
*Lo How a Rose E'er Blooming
*O Come Emmanuel (love the minor key)
*Ding Dong, Merrily on High (no laughing on this one!)
Christmas isn't Christmas without brass. Period. 
I have to thank you--I think--Eupher, sir.
As you know, I don't hear, no eardrums, no ears.
Actually I "can," through bone-conduction, where sounds reverberate through the skeletal structure. But it's very difficult and a markedly inefficient way to "hear."
When I was a little lad, my father, an ear physician, and some guy with
Popular Mechanics know-how contrived something that instead of blasting sound through the air, would blast sound directly into my orthopedic system.
It's about the size of a shoe-box.
It's very clumsy to use, and requires connections on both sides of my head (where ears would be if there were ears), the forehead, the throat, and the two elbows. And then of course one has to go through the time and trouble of connecting it to a stereo (LP; not usable for CDs or cassette tapes, being w-a-a-a-a-a-y too old for that). It's just a lot of hassle, a lot of trouble.
So as you could imagine, I don't do it a whole lot. Perhaps about an hour a year.
Well, your selections inspired me to do it anyway.
It takes a lot of really intense concentration.
So.....

Es Ist Ein Ros Entsprungen (Trapp Family Singers)
Deine Wangelen (Trapp Family Singers)
I know this isn't your standard Christmas music, but it works for me; there's a whole lot of different stuff more amenable to bone-conduction than other stuff, and generally most of the time usually secular happy-happy jolly-jolly Christmas music doesn't "travel" well, while medieval English carols and deep voices doing ancient Latin do.
