Actor-singer Cassidy bows at No. 27 sparked by social media interest following his Nov. 21 death of liver failure.

The late David Cassidy bows on the Social 50 chart (dated Dec. 9) at No. 27, following the 67-year-old's death on Nov. 21 of liver failure.

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 Nov. 23 and is led by K-pop kings BTS, at No. 1 for a 50th total week. Only Justin Bieber has led the list longer: 163 weeks to date.

Cassidy enters the chart after his Wikipedia page tallied 814,000 clicks in the week ending Nov. 23, a boost of 14,191 percent, according to Next Big Sound. The singer and actor, best known for his role as Keith Partridge on TV's The Partridge Family, notched multiple hits on the Billboard charts, with and without The Partridge Family, in a career dating back to the early 1970s. They include The Partridge Family's Billboard Hot 100 No. 1 "I Think I Love You" and his solo No. 9 hit "Cherish." He last hit the Hot 100 in 1990 (after an 18-year break) with his fifth top 40 solo hit, "Lyin' to Myself."

Elsewhere on the Social 50, Selena Gomez rockets 22-2 following a busy week that saw the singer celebrate the release of the music video for her Marshmello collaboration "Wolves" (which jumps 51-20 on the Hot 100); perform the song on the American Music Awards (Nov. 19); and debut her new footwear line partnership with Puma. (Oh, and she dyed her hair blonde, too.)

Gomez earned 51 million Instagram reactions, a boost of 1,727 percent, and added 433,000 Twitter mentions, the latter additionally assisted by rumors of her potentially on-again relationship with Justin Bieber.

Meanwhile, Post Malone ascends to a new Social 50 peak of No. 11 (from No. 32), passing his previous best of No. 18 (Oct. 21). The rapper made waves on Twitter with a Nov. 23 video attempting to clear up comments that he made about hip-hop in an interview with NewOnce, having said, "If you're looking to think about life, don't listen to hip-hop."

"I love hip-hop," he countered in the response video, addressing claims that he's not committed to the genre. The clip helped him to 225,000 Twitter mentions, a boost of 144 percent.
