Meek Mill is the top musical act in the U.S. again, leading the Billboard Artist 100 (dated July 25) for a second week.

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.

Meek Mill Reigns Again at No. 1 on Billboard 200 Chart

Meek Mill (born Robert Rahmeek Williams) rules the Artist 100 thanks, for a second week, largely to album sales, which account for 74 percent of his points on the chart. His Dreams Worth More Than Money spends a second week at No. 1 on Top Album Sales, with 240,000 copies sold, according to Nielsen Music.

Meek Mill is one of an elite seven acts, and two rappers, that have spent multiple weeks atop the Artist 100 (since the list's July 2014 launch). Taylor Swift is far out in front with 31 total frames on top, followed by Sam Smith, with three. Drake, Ariana Grande, Maroon 5 and Meghan Trainor have also each led the chart for two weeks.

Swift holds at No. 2 on the Artist 100, with radio airplay, album sales and digital song sales sharing a fairly equal split of her greatest drivers of activity. Rounding out the top five, The Weeknd stays at No. 3 and Ed Sheeran (5-4) and Maroon 5 (4-5) swap spots.

Just below the Artist 100's top 10, Rachel Platten climbs 20-15. The pop singer/songwriter hits a new peak in her 11th week on the chart, powered most strongly by digital sales of her breakout hit "Fight Song," which rises 10-8 on the Hot 100. Song downloads account for 62 percent of her Artist 100 action, followed by radio airplay (24 percent).
