Like music explicit about winter and how it makes you feel. Maybe think more yuletide than Christmas I suppose. Heavy on the pine wood forest and cold winter nights and light on the Jesus and love
The vibes don't have to be happy either, some songs by woods of ypres work as well
I have one that technically isn't much about religion, and has nothing on love
It's still Christmassy though (I mean its based it's basically an instrumental cover of one)
That being said, it's "Deadly Gentlemen", an FPS soundtrack...
