The K-pop boy band spends its 30th week on top.

BTS reclaims the top spot on Billboard's Social 50 chart, rising 2-1 for its 30th week at No. 1 on the list dated July 15.

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 June 29.

The K-pop boy band returns to No. 1 with boosts in Instagram followers, Instagram reactions, Twitter mentions and Twitter reactions in the tracking week, including a 57 percent jump in Instagram followers, according to Next Big Sound. While most posts showed the band on its current tour through Japan (with stops in Saitama and Fukuoka before reaching Sapporo), others included a song recommendation for Irish rockers JJ72's "Undercover Angel"; that band split in 2006 (and has never appeared on a Billboard chart in the U.S.).

Meanwhile, Tyler, The Creator returns to the Social 50 for the first time in more than a year, and for just a third week overall, at a new peak of No. 27. The rapper previously hit a No. 41 high a year ago. Tyler's resurgence is sparked by the release of a new song on June 29, "Who Dat Boy," his first new material as a lead artist since 2015's Cherry Bomb. (He followed the next day with another track, "911 / Mr. Lonely.") The Odd Future leader leaps 1,355 percent in Twitter mentions (to 56,000) and 526 percent in Twitter reactions (316,000), as he counted down the days to the release of "Boy" daily with images of talking bees.

Finally, Michael Jackson returns to the Social 50 at No. 35, marking his first appearance on the chart since Feb. 21, 2015. The catalyst is a 20 percent bump in Wikipedia views (521,000 overall) and a 355 percent gain in Twitter mentions (20,000), mostly around posts from users on social media commemorating the anniversary of Jackson's death eight years ago (June 25, 2009). Jackson's official Twitter and Facebook accounts also shared a few words on the anniversary.
