It’s the holiday song that gets stuck in your head year after year.

Mariah Carey’s “All I Want for Christmas Is You” added another milestone to its list: the song now ties for the most weeks ever spent at No. 1 on the Billboard Hot 100, hitting its 19th week on top. That puts the track alongside Old Town Road and A Bar Song (Tipsy) in Hot 100 history.

The 1994 Christmas anthem’s climb reflects the enduring power of holiday nostalgia in the streaming era — even decades after its release, it still resonates broadly as the calendar flips toward the holidays. Each December, the track re-enters playlists, radio rotations, and streaming queues, feeding a surge in popularity that pegs it at the top.

That resurgence demonstrates how modern consumption habits — streaming, digital sales and airplay — can transform a seasonal classic into a perennial chart force. For Carey, it’s another chapter in a legacy already defined by megahits, chart records and festive dominance.

Across the years, “All I Want for Christmas Is You” has proven unusually resilient. Once a holiday-only offering, it now returns annually and dominates the charts, showing that a well-timed song can become a cultural evergreen. For the 2025 holiday season, the 19th week atop the Hot 100 underscores the song’s ability to outlast generations of musical trends.

As the song heads into its 20th stretch at No. 1, many are watching to see if it will claim sole ownership of the record. Whichever way it goes, the 2025 return adds another notch to a rare feat — turning a Christmas song into one of the most dominant singles in chart history.
