As Australian band 5 Seconds of Summer rises 5-2 on Billboard's Social 50 chart, their British counterparts the Vamps debut at No. 34. It's the first appearance on any U.S. Billboard chart for the Vamps.
While both acts are not your standard boy band -- since they are actual bands instead of singing-and-dancing vocalists -- they both still appeal to the female tween-and-teen demographic (a boy band’s core audience).
The Vamps (comprising Connor Ball, Tristan Evans, James McVey and Brad Simpson) enter the Social 50 from activity generated by the announcement of their forthcoming EP, "Somebody to You," due out Aug. 5, and a concert date in the U.K. on June 22.
Photos from the performance at North East Live festival caused a 322 percent increase in Instagram reactions in the week ending June 22, according to Next Big Sound, and sparked more than 320,000 stories about the group on Facebook (a 25 percent increase over the previous week).
More boy band fun: the Vamps are managed by Prestige Management, who also manage British pop/rock band McFly. Meanwhile, 5 Seconds of Summer share the same management as One Direction (who hold at No. 14).
Elsewhere on the Social 50, World Cup excitement spurs a big jump for Rihanna, as the diva vaults 43-29. She tallied a 199 percent gain in both mentions and retweets on Twitter for the week, thanks to her passionate Tweets during World Cup matches.
Back in the top 10, Justin Bieber holds at No. 1 while Tyrese climbs 8-3 and Jennifer Lopez slips 2-4. Miley Cyrus drops 3-5, Pitbull steps 7-6 and La Arrolladora Banda El Limon De Rene Camacho slips 6-7. Ariana Grande descends 4-8, Taylor Swift is steady at No. 9 and Selena Gomez rises 13-10.
