Which holiday song became Mariah Carey’s 19th Billboard Hot 100 No. 1?

Mariah Carey’s “All I Want for Christmas Is You” became her 19th Billboard Hot 100 No. 1.

The song first appeared on Carey’s 1994 holiday album Merry Christmas, but its chart peak came decades later. It reached No. 1 for the first time in December 2019, making Carey the first artist to collect 19 Hot 100 leaders. Its seasonal popularity has continued to return it to the upper reaches of the chart in subsequent holiday periods.

Carey co-wrote and co-produced the recording with Walter Afanasieff. The track uses sleigh bells, a brisk pop arrangement, and a direct romantic lyric rather than focusing on presents or traditional Christmas imagery. That combination helped it become a modern holiday standard.

The song is often confused with Carey’s earlier No. 1 total or with her record for weeks at the summit. The precise milestone here is the number of her career-leading singles: the Christmas song was No. 19.
