The group takes over at the top, fueled by No. 1 start on the Billboard 200. Also jumping: OneRepublic and Jason Aldean.
The list, which launched three weeks ago, provides the first-ever weekly ranking dedicated to measuring artist activity across Billboard's most influential charts, including the Billboard Hot 100, Billboard 200 and Social 50, among others. The Artist 100 is modeled after the formula utilized to compile Billboard's annual Year in Music Top Artist list (as well as the Billboard Music Awards Artist of the Year category), blending information from album and track sales, radio airplay, streaming and social media fan interaction to provide a weekly multi-dimensional ranking of artist popularity.
As the band debuts atop the Billboard 200 with its self-titled debut full-length album, 5 Seconds of Summer likewise crown the Artist 100. Not surprisingly, the album's lofty opening-week sales (259,000, according to Nielsen SoundScan) account for 89 percent of the pop group's Artist 100 points total.
Smith sports a more even spread of Artist 100 points, thanks to the success of his album In the Lonely Hour and its smash hit "Stay With Me." The set rebounds 6-4 on the Billboard 200 with 31,000 copies sold, marking 25 percent of his points sum. "Stay" ranks at No. 3 on the Billboard Hot 100 for a second week, with his songs' airplay (including that of Disclosure's "Latch" and Naughty Boy's "La La La," on which he's featured) accounting for the highest share of his points (26 percent). (An act in a featured role claims a smaller portion of a song's overall points than the lead act for purposes of the Artist 100's tabulation.)
Iggy Azalea (2-3), MAGIC! (4-4) and Ariana Grande (7-5) round out the Artist 100 top five, while OneRepublic jump 11-6, due, like Smith, to multiple factors, including the band's notable radio presence and the bow of its iTunes Sessions on the Billboard 200 (No. 117; 3,000 sold). The group's overall digital song sales account for the largest slice of its Artist 100 points (33 percent), followed by album sales (27 percent) and radio airplay (26 percent). OneRepublic's current single "Love Runs Out" rises 11-10 on Radio Songs, where it's the band's fifth top 10, with 62 million in audience, according to Nielsen BDS; previous smash "Counting Stars" ranks at No. 25 with 44 million.
A pair of star country acts, Florida Georgia Line (8-7) and Luke Bryan (12-8), follow on the Artist 100, while Pharrell Williams soars 16-9, fueled by the 60-23 Hot 100 jump for his "Come Get It Bae" after the July 23 release of the song's video (featuring a guest vocal from Miley Cyrus). Whereas Williams' streaming activity was the third-biggest portion of his Artist 100 points last week (after digital song sales and airplay), this week it's first. "Bae" enters Streaming Songs at No. 14 with 3.8 million U.S. streams, up 452 percent.
Rounding out the Artist 100's top 10, Jason Aldean blasts 72-10 for his first week in the top tier. (He ranked at No. 69 when the chart launched and rose to No. 64 the following week.) As "Burnin' It Down," the lead single from his forthcoming sixth album, debuts at No. 12 on the Hot 100 and No. 1 on Digital Songs with 184,000 first-week downloads sold, digital song sales contribute 71 percent of his Artist 100 points sum (up from a 22 percent last week).
