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 hate xmas. I hate xmas music because it triggers my working in retail PTSD.
The only music I can tolerate are the Bells and any Tchaikovsky because the Nutcracker slaps.
