Louis Tomlinson vaults 38-7 on Billboard's Social 50 chart dated April 15, boosted by buzz generated from his March 25 performance at Ultra Music Festival alongside Steve Aoki. Meanwhile, his fellow One Direction member Liam Payne returns to the chart at No. 28 (more on that in a moment).
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, Instagram 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 on March 30.
Tomlinson joined Aoki for a performance of the duo's "Just Hold On" at the fest, a day removed from the release of a remix EP for the track that included Aoki's festival edit of the song, which peaked at No. 52 on the Billboard Hot 100 (Dec. 31, 2016). After not posting to Twitter or Instagram for the previous week or so, Tomlinson nets 715,000 Twitter reactions and 1.1 million Instagram reactions in the week ending March 30, according to Next Big Sound.
"Thank you for giving me the confidence to do shit like that!" he wrote in one tweet.
Tomlinson isn't the only member of One Direction to make a splash on the Social 50. Liam Payne, celebrating the birth of his first child (with Cheryl Cole) on March 22, re-enters at No. 28, his highest rank since January, with rises of 454 percent in Twitter mentions (146,000).
"Thank you to everyone for the love and supportive messages for myself and @CherylOfficial," Payne tweeted on March 27. "It really means a lot."
Meanwhile, Gorillaz makes its first appearance on the chart, debuting at No. 19 following the release of four new songs and a music video, plus the announcement of new album Humanz (out April 28).
The cartoon group leaps in YouTube reactions (820,000) and subscribers (294,000), thanks in large part to two different videos for "Saturnz Barz" -- a static video and the other with the capability for viewers to spin the vantage point 360 degrees.
The group also jumps 333 percent in Wikipedia views, to 305,000 overall.
