The lead single on Carey's 1994 holiday album Merry Christmas, the track has sold over 16 million copies worldwide, making the songstress more than $60 million (£47m), and is said to continue to pull in royalties of around $500,000 (£393k) a year.
In 2019, Carey marked the 25th anniversary of her iconic song, and it topped the Billboard 100 for the first time since its release. Christmas is definitely the money-making season for the pop star and in 2020 she probably earned more than ever. Carey fronted Mariah Carey's Magical Christmas Special on AppleTV+, a Christmas TV show that's thought to have hit the number one spot for the streaming service in more than 100 countries. Featuring Ariana Grande, Jennifer Hudson, Snoop Dogg and others, the show also boasted an accompanying soundtrack.
