Mariah Carey is proving her holiday power…

The 51-year-old half-Venezuelan American Grammy-winning songstress’”All I Want for Christmas Is You” is the biggest song in the world for a second week, as her 1994 carol spends a second frame at No. 1 on the Billboard Global 200 chart.

Carey’s insta-classic holiday single tops the Billboard Global 200 for a second week, up 6% to 83.7 million streams and 19% to 21,000 sold worldwide in the week ending December 17.

The song was first released on Carey’s 1994 holiday album Merry Christmas.

The chart (dated December 26) 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.
