The K-pop boy band spends its 52nd week atop the ranking.

Late French rock 'n' roll legend Johnny Hallyday makes his Billboard chart debut, bowing at No. 11 on the Social 50 chart dated Dec. 23 following his Dec. 6 death.

The Social 50 is powered by data tracked by music analytics company Next Big Sound and ranks the most popular artists on Facebook, Twitter, Instagram, YouTube, Wikipedia and Tumblr. The chart's methodology blends weekly additions of friends/fans/followers along with artist page views and engagement.

The chart’s latest tracking week ended Dec. 7, and BTS is No. 1 for a 52nd nonconsecutive week, and the 22nd week in a row. Since debuting on the list dated Oct. 29, 2016, BTS has never ranked below No. 2. That sustained strong performance resulted in the act being named the year-end top Social 50 artist.

Among all acts, only Justin Bieber has more weeks at No. 1 on the weekly chart, with 163.

Meanwhile, Hallyday, who mostly recorded in French during a career that spanned over a half-century but also released occasional English-language albums (though he never earned crossover success in the U.S.), debuts at No. 11 after he received 898,000 Wikipedia views in the Dec. 1-7 tracking week and was mentioned 40,000 times on Twitter, according to Next Big Sound.

Halladay died at age 74 of lung cancer outside Paris. He was honored on Instagram by Ed Sheeran, who called him a “true gent” in a Dec. 6 photo of the pair. Sheeran jumps 25-6 on the Social 50 with a 216 percent boost in Instagram reactions, helped in part by his photo with Hallyday.

Additionally, Sheeran’s Instagram bump was assisted by two photos from the Dec. 7 ceremony where he accepted his Member of the Order of the British Empire honor for his contributions to charity as well as his musical endeavors. He also posted about the track list to Eminem’s album Revival, on which Sheeran is a featured artist and co-writer on the song “River.”

One spot below Sheeran at No. 7 on the Social 50, Taylor Swift re-enters following a flurry of activity on her Instagram page, garnering 16.4 million reactions overall (up 2,733 percent). The singer, in addition to posting shots from her Vogue cover photoshoot, also shared the magazine cover for Time’s person of the year issue on which she was featured among the “Silence Breakers,” a collection of women who railed against harassment and sexual assault in 2017.
