The country group zooms 40-1 thanks to the arrival of its new album. Plus, moves for Josh Groban, David Guetta, Rachel Platten & Tori Kelly.

The Artist 100 is the first weekly survey dedicated to measuring artist activity across Billboard's most influential charts, including the Billboard Hot 100 songs chart, Top Album Sales and the Social 50. The Artist 100 blends data measuring album and track sales, radio airplay, streaming and social media fan interaction to provide a weekly multi-dimensional ranking of artist popularity.

Up 692 percent in overall activity, Zac Brown Band rules the Artist 100 as its Jekyll + Hyde launches atop the Billboard 200, with 228,000 equivalent album units in the week ending May 3, according to Nielsen Music, and Top Album Sales (214,000 in traditional album sales). Album sales account for 90 percent of the group's Artist 100 points.

ZBB becomes the fourth country act (excluding the now pop-focused Swift) to lead the Artist 100, following Blake Shelton, Jason Aldean and Florida Georgia Line. Those three acts reigned consecutively in October-November, also thanks to No. 1 Billboard 200 bows.

Rounding out the Artist 100's top five, Josh Groban debuts at No. 2, as his new LP Stages enters Top Album Sales at No. 2 (176,000 sold); Swift descends 1-3; Wiz Khalifa drops 2-4; and Maroon 5 holds at No. 5.

In other Artist 100 action, David Guetta becomes just the second DJ to hit the chart's top 40, as he lifts 45-37 (up 13 percent). Calvin Harris first reached the region, peaking at No. 9 in November. Digital song sales mark Guetta's biggest points contributor (56 percent), as his "Hey Mama" (featuring Nicki Minaj and Afrojack) tops Hot Dance/Electronic Songs for a third week.

Floyd Mayweather Jr. and Manny Pacquiao have made the biggest headlines regarding fighting of late, following their pop-culture-conquering May 2 bout, but pop singer/songwriter Rachel Platten answers the bell on the Artist 100, debuting at No. 75 thanks to the success of her single "Fight Song." The Massachusetts native's hit packs a big punch on the Hot 100 (71-50) and Digital Songs (31-22), up by 47 percent to 54,000 downloads sold. Digital song sales account for the majority (78 percent) of Platten's Artist 100 points.

Platten sang "Fight Song" on the Radio Disney Music Awards (April 29, broadcast on Disney Channel).

Fellow rising pop act Tori Kelly enters the Artist 100 at No. 88. Song sales likewise carry the bulk of her standing (71 percent), as her breakthrough single "Nobody Love" hits a new high on the Hot 100 (67-60) and Digital Songs (45-27; 42,000 sold, up 43 percent).
