I have this CD called "Joy To The World, an other songs done in organs and chimes". I am not saying it is my favorite, but the LP version my parents had in the 60s, and played on what would be a console Hi-Fi then, sounded very close to a real church organ. The CD pales in comparison, in that it completely loses the low end that made the LP great.
Other than that, I have no favorite Christmas CDs or otherwise, but strongly prefer a good part of the middle 1950s to the 1970s mostly traditional music, as well as the way Christmas looked back then, especially in Kodachrome pictures.
