Best Christmas song to re-enter the Billboard US Hot 100 in 2019

didn't expect this winner

Mariah (25), Brenda (41) and Bobby (50) all re-entered the countdown this week, so tis the season. With "Jingle Bell Rock," I do wonder: does Mean Girls fandom have anything to do with its contemporary popularity (relative, that is--I realize that film is nearly 20 years old now), or has this song always been bigger than, say, any given version of "Silent Night" or "Frosty the Snowman" or anything like that?

I just learned via Andrew Hickey that “Feliz Navidad” was produced by the same guy who produced Surrealistic Pillow for the Jefferson Airplane.
