This is only the second holiday song to reach the top five on this chart (the first was ‘The Chipmunk Song’ way back in 1958). It likely would have done so much sooner but for years Billboard’s rules prevented holiday songs, and then “recurrent” songs, from appearing on the Hot 100. The latter rule was changed in 2012, and the track has hit the Hot 100 several times since.
Mariah Carey’s ‘Emotions’ was her fifth number one hit in a row (making her the only artist to ever have her first five singles reach #1). She dominated the airwaves in the early 90s the way Katy Perry has twenty years later.
