I Wonder as I Wander-Lindsey Stirling (from her Christmas Album, but it's original. Very cool. I hope she releases a new album in the beginning of next year though. Since we don't get any more Kalafina... *sigh*)
Ring Your Bell with strings ver-Kalafina (wow, I like this a lot. Better than what they had been doing with the first part being only piano, and then starting with the whole band. I would love to see Wakana sing this at one of her lives. *sigh* If only I had money to go to Japan, and the time and wasn't afraid of flying, or had a cat lol)
Winter Acoustic with Strings, Seiya, Charlie Brown Christmas, Phil Spector Christmas Gift, June Christy This Time of Year, Cocteau Twins Snow EP, some Bing Crosby, and a few other Kurisumasu songs that I can tolerate.
