Mariah Carey has 100 reasons to smile…

The 56-year-old half-Venezuelan American Grammy-winning singer’s “All I Want for Christmas Is You” adds a record-extending 21st week at No. 1 on the Billboard Hot 100.

Carey claims her unprecedented and milestone 100th career week at No. 1 on the Hot 100, having accumulated her haul over 19 leaders, dating to her first, “Vision of Love,” in 1990.

Rihanna ranks second with 60 weeks at No. 1, followed by The Beatles (59) and Drake (56).

“All I Want for Christmas Is You” secures another notable record as it logs its 78th week on the Hot 100, surpassing Dua Lipa’s “Levitating” as the longest-charted title ever by a woman artist.

Two weeks earlier, “All I Want for Christmas Is You” returned to No. 1 on the Hot 100 to lead in a record-extending seventh holiday season.

It arrived on Carey’s album Merry Christmas in November 1994 and, as streaming grew and holiday music became more prominent on streaming services’ playlists, it first hit the top 10 in December 2017 and the top five in the 2018 holiday season.

It led at last, prior to its three weeks this season, over the holidays in 2019 (for three weeks), 2020 (two), 2021 (three), 2022 (four), 2023 (two) and 2024 (four). (Older holiday songs are eligible to appear on the chart each season.)

The Hot 100 blends all-genre U.S. streaming (official audio and official video), radio airplay and sales data, the lattermost metric reflecting purchases of physical singles and digital tracks from full-service digital music retailers; digital singles sales from direct-to-consumer (D2C) sites are excluded from chart calculations.

“All I Want for Christmas Is You,” on Columbia Records/Legacy Recordings, drew 43.6 million streams (up 10%) and 28 million radio airplay audience impressions (up 24%) and sold 3,000 downloads (up 1%) in the U.S. December 12-18, according to Luminate.

The single holds for a record-extending 25th week atop the Streaming Songs chart; dashes 23-15 on Radio Songs, where it has hit a No. 7 best; and stays at No. 5 on Digital Song Sales, following six weeks on top.

“All I Want for Christmas Is You” concurrently tops Billboard’s multimetric Holiday 100 chart for a 70th week, of the chart’s 78 total weeks since the survey originated in 2011.

It leads the Holiday Streaming Songs, Holiday Airplay and Holiday Digital Song Sales charts concurrently for the first time this season, and triples up as the top Yuletide title in all three metrics simultaneously for a record 28th time. Since the three charts began coexisting in December 2013, no other song has led them all at the same time even once.
