The music of the anime just pales when compared to the game, to me they just don't have capture that winter atmospheric feel like the original soundtrack has.
I have no idea why they have to remove the
original title song when it works fine even after all these years. (It's been on my playlist for every Christmas for about a decade.) Less can be said about the ED. Maybe it's because they sound too 90's ?
Let's hope they retain the game's soundtrack instead of taking anime's now.
Edit :- Whaddaya know, after running a search for the music files on the cluttered maze that is my HDD, I found I have the English Vocal Soul-dified version of Powder Snow (Game ED) . The lyrics is certain touching :-
