The Weeknd remains at No. 1, while Sheeran leaps thanks to increased social reaction.

The Weeknd remains the top musical act in the U.S., holding at No. 1 on the Billboard Artist 100 chart (dated Jan. 21).

The Artist 100 measures artist activity across Billboard's most influential charts, including the Billboard Hot 100, Top Album Sales and the Social 50. The Artist 100 (which launched in July 2014) 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.

The Weeknd leads the Billboard Artist 100 chart for a 12th total week, with streaming accounting for the greatest share of his chart action (38 percent), led by single "Starboy" (featuring Daft Punk), which ranks at No. 4 on the Streaming Songs chart with 22.3 million U.S. streams in the week ending Jan. 5, according to Nielsen Music.

Drake rises 3-2 on the Artist 100. With 23 total weeks at No. 1, he is the only male artist to spend more time at the summit than The Weeknd (while, among all acts, only Taylor Swift has logged more weeks at No. 1 than Drake and The Weeknd: 31). Rounding out the Artist 100's top five, Bruno Mars lifts 4-3; twenty one pilots push 5-4; and Shawn Mendes climbs 7-5.

Meanwhile, Ed Sheeran soars 97-29 on the Artist 100, up 117 percent in overall activity. The singer-songwriter (who topped the Sept. 5, 2015, chart) should vault further next week, with his two new singles, "Shape of You" and "Castle on the Hill," set to storm the Hot 100 following their Jan. 6 release. On the Social 50, Sheeran re-enters at No. 5, marking his best rank in his 105 total weeks on the tally (and his first appearance in the top 10 since March 21, 2015).
