Taylor Swift No. 1 on Artist 100 for 13th Week, Prince Royce Debuts

Atop the Artist 100, as Swift's 1989 crowns the Top Album Sales chart for a ninth week with 111,000 sold; album sales mark her top Artist 100 contributor (45 percent). Digital song sales follow at 27 percent.

Prince Royce roars onto the Artist 100 thanks to "Stuck," which, belying its title, shifts into high gear on the Hot 100, jumping 78-63 in its third week on the chart. Social metrics account for the majority of his Artist 100 standing (41 percent), as he blasts 38-13 on the Social 50. Airplay follows at 29 percent, as the track gains by 19 percent to 29 million in all-format radio audience, according to Nielsen Music. Digital song sales account for 19 percent of his Artist 100 total, with the song up by 33 percent to 21,000 sold in the week ending Jan. 11.

"Stuck" previews Prince Royce's forthcoming first English-language album. He's tallied three No. 1s on Top Latin Albums beginning in 2011.

Meanwhile, Hozier reaches the Artist 100's top five for the first time (6-5). Digital song sales account for the majority (42 percent) of the Irish singer/songwriter's activity on the chart.

Mark Ronson, Bruno Mars No. 1 on Hot 100 for Second Week With 'Uptown Funk!'

In another Artist 100 highlight, Mark Ronson reaches the top 10 (13-8), fueled by "Uptown Funk!," featuring Bruno Mars, which leads the Hot 100 for a second week. Digital song sales drive two-thirds of Ronson's Artist 100 activity. Following the arrival of his album Uptown Special on next week's Billboard 200, he should further challenge for the Artist 100's top spot.

Joining Swift, Hozier and Ronson in the Artist 100's top 10, Ed Sheeran, Sam Smith and Nicki Minaj hold at Nos. 2-4, respectively. Meghan Trainor dips 5-6; Rae Sremmurd blasts 29-7 as its debut album, SremmLife, enters the Billboard 200 at No. 5; Ariana Grande slips 8-9; and Beyonce stays at No. 10.
