Favourite Christmas Carol & Song?

I thought this might be an interesting thread to create seeing as it's almost Christmas and wherever you might be you are probably hearing most of them at the moment. 😜

I don’t really have any favourite Christmas carol actually, but if I had to pick one I’d go with “Silent Night” I guess. However, I have plenty of songs I don’t mind.

Favourite Christmas song (in no particular order):

All I Want For Christmas Is You - Mariah Carey
Do They Know It's Christmas - Band Aid (1984 version)
Last Christmas - Wham!
Happy Xmas (War Is Over) - John Lennon
Rockin Around The Christmas Tree - Brenda Lee - I mainly like this one because it’s featured in one of mine (and a few of yours) favourite movie! 
Aussie Christmas - Bucko and Champs - I also don’t mind a few of the tracks on this 1996 album release by Colin Buchanan and Greg Champion with their own spin on Christmas classics.

So, what about you guys, what’s your favourite(s)?
