I know the Mariah Carey song is hated because its overused, but its also objectively a well produced piece of pop music.
My favorite though is O Holy Night. Performed well I want to stop and listen to it. It moves me, and I dont give enough of a fuck about religion to call myself an athiest.
As an atheist, I don’t like religious xmas music. But I love these songs based on the Cthulhu Mythos. The HP Lovecraft Historical Society did a fantastic job on them! I have 2 CDs of xmas holiday music from them (much more than this playlist has), and an adaptation of The Fidder on the Roof called A Shoggoth on the Roof.
