I do not believe anyone has asked this here yet this season, so I'll start. Here is my all time favorite....
Mary did you Know? Written by Mark Lowry. Here it is sung by Pentatonyx...

Kathy Mattea also does a nice rendition of this. So does Peter Hollens.
For something a bit less known and different, one of my favorite Christmas albums is Rodger Whittaker's Christmas album, done back in 1978 Here it is on Youtube;

I know there are many others....Karen Carpenter's Ava Maria gives me goosebumps even after all these years...
What are yours?
