Adele Holds Atop Billboard Artist 100 Chart

Adele attends the television show 2015! Menschen, Bilder, Emotionen - RTL Jahresrueckblick on Dec. 6, 2015 in Cologne, Germany. 

With another million-selling week for '25,' Adele stays at No. 1 on Billboard's weekly artist survey.

As new album 25 continues to make history, Adele is again the top musical act in the U.S., keeping at No. 1 on the Billboard Artist 100 chart (dated Dec. 19).

The Artist 100 measures 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.

Adele's '25' Set to Pass 5 Million Sales Mark

Adele leads the Artist 100 for a fourth total (and second consecutive) week with a more than two-to-one lead in points over runner-up Justin Bieber (at No. 2 for a second week), despite her 46 percent decrease in overall activity. Of course, that precipitous drop is from record-breaking heights -- she still notched some record-setting figures this week. As previously reported, the set scores a historic second week at No. 1 on the Billboard 200 and Top Album Sales, earning 1.16 million equivalent album units in the U.S. in the week ending Dec. 3, according to Nielsen Music. Of that sum, 1.11 million were in pure album sales. After opening with a record 3.48 million (3.38 from pure sales), 25 is the first album to sell at least 1 million copies in two separate weeks since Nielsen began tracking sales in 1991.

Album sales continue to mark Adele's greatest metric on the Artist 100 (72 percent; last week the mark was 81 percent). Digital song sales follow at 15 percent.

Below Adele and Bieber, Drake and The Weeknd remain at Nos. 4 and 5 on the Artist 100, respectively, with Taylor Swift (6-5) rounding out the top five.
