Mariah Carey’s global domination during the holiday season is complete…

The 51-year-old half-Venezuelan American singer’s “All I Want For Christmas Is You” is officially the biggest song in the world, as it rises to No. 1 on the Billboard Global 200 chart twenty-six years after its original release.

Carey’s insta-classic Christmas track rises from No. 2 to No. 1 on the Billboard Global 200, up 19% to 79.3 million streams and 18% to 17,000 sold worldwide in the week ending December 10.

The song, first released on Carey’s 1994 album Merry Christmas, returns to No. 1 on the U.S.-based Billboard Hot 100, which it led for the first time last holiday season.

Meanwhile, Carey’s “All I Want For Christmas Is You” jingles 3-2 on the Global Excl. U.S. chart, with 51.4 million streams (up 20%) and 10,000 sold (up 27%) outside the U.S.

The charts (the latest of which is dated December 19) premiered in September and ranks songs based on streaming and sales activity culled from more than 200 territories around the world, as compiled by Nielsen Music/MRC Data. The Billboard Global 200 is inclusive of worldwide data.

Chart rankings are based on a weighted formula incorporating official-only streams on both subscription and ad-supported tiers of audio and video music services, as well as download sales, the latter of which reflect purchases from full-service digital music retailers from around the world, with sales from direct-to-consumer (D2C) sites excluded from the charts’ calculations.
