I've been mulling this one over for a while, trying to figure out what I thought was the worst and I've come up empty...I know I don't care much for the "Very Special Christmas" series after the second one, and I have several songs that I don't like (i.e. Grandma Got Run Over By a Reindeer, Domenick the Donkey...That crappy Britney Spears song on the second "Now That's What I call Christmas" series...) but I don't have a whole album I hate. I'd have an even harder time to tell you what my favorite one is though!
Nothing is more important than the soundtrack!!!
