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.
I’ve always thought it sounds like a horror song as well, which is why my favorite version is by the Lovecraft historical society: Carol of the old ones
