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.
The only Christmas-related media I like in any capacity, is the OG Grinch cartoon. So Thurl Ravenscroft is the only person I wanna hear singing on Christmas.
