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.
Regardless of home alone, every version of Carol of the Bells I’ve heard is great. And it sounds like a horror movie theme so I listen to it throughout the year.
