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.
Not sure if it counts, but John Coltrane playing “My Favorite Things”. I got that track on some best of Coltrane collection for Christmas when I was in grade school. It eventually became both my favorite Christmas song and really got me into jazz. It’s still the default version that pops into my head when I think of that song, not Julie Andrews singing it in The Sound of Music.
