Justin Bieber shows surprises the crowd for a surprise performance with Chance The Rapper on day 3 of the 2014 Coachella Valley Music & Arts Festival on April 13, 2014 in Indio, California.
During a slow week on the Social 50 chart, the first weekend of the Coachella festival (April 11-13) in Indio, Calif. spurs some big gains for a couple of superstar acts.
The Social 50 ranks the most popular artists on YouTube, Vevo, Facebook, Twitter, SoundCloud, Wikipedia, Myspace and Instagram. The chart's methodology blends weekly additions of friends/fans/followers along with artist page views, song plays and reactions as measured by music analytics company Next Big Sound.
Justin Bieber, who made an unannounced appearance during Chance the Rapper's set on April 13, sees a 15 percent rise in overall chart points and remains at No. 1. The duo performed their collaboration "Confident," which hit No. 13 hit on Hot R&B/Hip-Hop Songs last year. The buzz helped make Chance the sixth most-mentioned performer of the weekend (according to Twitter).
Bieber shared a video of the surprise performance to his Instagram account, which snagged more than 750,000 likes. That helped Bieber net a 97 percent rise in engagement on the platform through the week ending April 13, and add an overall 636,000 new fans to his audience.
Elsewhere on the Social 50, Beyonce dances up 14-8 thanks to a surprise appearance with her sister Solange on April 12. During Solange's performance of "Losing You," Beyonce emerged from backstage and the two did a short choreographed dance number together (though Bey did not sing). Beyonce saw a 135 percent rise in reactions across Facebook, Twitter and Instagram. On Twitter alone, where mentions of Beyonce climbed by 84 percent, she added 56,000 new followers.
The rest of the top 10 is fairly static, as Shakira, Miley Cyrus and Katy Perry all hold at Nos. 2-4, respectively. Ariana Grande rises 6-5, Taylor Swift dips 5-6 and Eminem holds at No. 7. Pitbull descends a rung to No. 9, and Demi Lovato returns to the top 10, rising five slots to No. 10.
