Pretty much listened to this song a lot during November and December...

It has a very Christmas-like vibe to me for some reason, it has nice Strings(synthesized strings most likely), and the Piano(which is usually buried and hidden in the songs mix for the most part, which means the Piano for the most part serves as a textural compoment then anything else.).
