Mariah Carey first to score #1 hit in four different decades

Mariah Carey (pictured December 2019) has had a number one single on the Billboard charts in the 1990s, 2000s, 2010s and 2020s

Pop diva Mariah Carey has had a long list of hits over the years, but her classic holiday song has helped her make history as the first artist to top the Billboard charts in four separate decades.

"All I Want For Christmas Is You" is number one on the Billboard Hot 100 for the week dated January 4, 2020, based on sales, radio airplay and streaming data -- its third week atop the rankings.
