Holiday Song Brain Twister

Last week while surfing blogs I came across this fun play on song titles. I can't remember where I found it, but I saw it on two different blogs. I saved it so that I could go back and figure it out during my leisure time. I thought some of you might like to challenge your brain and see how many you can figure out. (I hope it is not someone's original game that I should not be posting...I can't give credit to where I found it because I did not save the url)
I put the answers in the comments.
