Wham!’s “Last Christmas” becomes the second holiday song in the one-year history of the TikTok Billboard Top 50 chart to hit No. 1, lifting 7-1 on the Jan. 4, 2025-dated tally.

The TikTok Billboard Top 50 is a weekly ranking of the most popular songs on TikTok in the United States based on creations, video views and user engagement. The latest chart reflects activity from Dec. 23-29. Activity on TikTok is not included in Billboard charts except for the TikTok Billboard Top 50.

“Last Christmas” reigns for the first time after reaching No. 2 a year before on the Jan. 6 survey, behind Mariah Carey’s “All I Want for Christmas Is You.” (Carey’s classic appears at No. 3 on the latest list.)

Concurrently, “Last Christmas” rises 51% in official Billboard-eligible U.S. streams to 69.6 million listens in the week ending Dec. 26, according to Luminate. It holds at its No. 3 peak on the multimetric Billboard Hot 100, which Carey’s “All I Want for Christmas Is You” rules for an 18th week.

Holiday-related music occupies 10 spots of TikTok Billboard Top 50, including four of the top 10; Jose Feliciano’s “Feliz Navidad” re-enters the chart at No. 8, a new peak, while Brenda Lee’s “Rockin’ Around the Christmas Tree” jumps 18-9.

Christmas music dominates the ranking due to the holiday falling amid the tracking period on Dec. 25, begetting a variety of uploads, from dances and lip syncs to creators showing off their gift hauls for the year.

The chart’s top 10 features another newcomer in the top 10, albeit not a Christmas song: Naughty Boy’s “La La La,” featuring Sam Smith, which leaps 19-4 in its second week on the tally.

Though some of the uploads using “La La La” use the original version, a majority of the top-performing clips feature a sped-up sound, generally set to a dance trend.

“La La La” sports a 165% jump in listens to 3.3 million streams in the week ending Dec. 26. It peaked at No. 19 on the Hot 100 in May 2014, Smith’s first appearance on the list.
