Which song gave Mariah Carey her longest-running solo reign at No. 1 on the Billboard Hot 100?

“All I Want for Christmas Is You” gave Mariah Carey her longest-running solo reign at No. 1 on the Billboard Hot 100.

The Christmas song first appeared on Carey’s 1994 holiday album Merry Christmas. It eventually reached No. 1 in 2019, 25 years after its release, as streaming and seasonal listening became major parts of the chart. The song has since returned to the summit during multiple holiday seasons.

Its chart performance is unusual because it is a seasonal recording rather than a conventional contemporary single. Christmas music can re-enter charts every year, and concentrated holiday listening allows the biggest seasonal titles to compete successfully with current releases.

Carey had already achieved many No. 1s with songs such as “Fantasy,” “One Sweet Day,” and “We Belong Together.” The holiday hit surpassed those songs in total weeks at the summit as her longest-running solo No. 1. It is also commonly discussed separately from Carey’s collaborative chart records.
