Mariah Carey has already solidified her holiday legacy with “All I Want For Christmas Is You,” which likely will climb back up to #1 on the Billboard charts just like last year. And she has embraced her role as the patron saint of Christmas songs. Last year, she put together an Apple TV+ event called Mariah Carey’s Magical Christmas, which came with a new track, “Oh Santa!,” that featured Ariana Grande and Jennifer Hudson.
