Some of my favorite Christmas albums:
-James Taylor at Christmas
-Amy Grant Christmas Album (I know... kickin' it old school)
-Chris Rice-- The Living Room Sessions- Christmas
-Sarah McLaughlan- Wintersong
Possibly my favorite Christmas song ever is "God Rest Ye Merry Gentlemen/We Three Kings" by the Barenaked Ladies with Sarah McLaughlan... which is saying A LOT because I generally despise "we three kings"
Without a doubt the worst Christmas album ever is Rosie O'Donnell's "a rosie christmas" It's SERIOUSLY bad.
