Rihanna’s “Work,” featuring Drake, spends a fourth week at No. 1 on the Billboard Hot 100 (dated March 26). Plus, Lukas Graham’s “7 Years” crowns the Digital Songs chart, Mike Posner’s “I Took a Pill in Ibiza” rises to the Hot 100’s top 10 and Meghan Trainor’s “No” debuts just beyond the top bracket, while making a big first-week splash in sales and airplay.

“Work,” released on Westbury Road/Roc Nation, also claims a fourth week atop the Streaming Songs chart with 36.9 million U.S. streams, down 8 percent, in the week ending March 10, according to Nielsen Music. The lead single from Rihanna’s album Anti also tops the subscription services-based On-Demand Songs chart (16.3 million, down 14 percent) for a fifth frame. It drops 2-3 on Digital Songs (109,000 downloads sold, down 29 percent), which it led for two weeks, and rises 4-3 on Radio Songs (113 million in airplay audience, up 8 percent).

“Work” rules Billboard’s Hot R&B/Hip-Hop Songs chart for a sixth (nonconsecutive) week. As reported when the song reached No. 1, “Work” is Rihanna’s 14th Hot 100 leader, upping her into a solo share of the third-most No. 1s all-time, passing Michael Jackson (13). The Beatles lead with 20 No. 1s, followed by Mariah Carey (18). “Work” is also the record-breaking ninth Hot 100 No. 1 in a row by non-U.S.-born acts (Rihanna is from Barbados; Drake, from Canada), while this week marks the record-extending 36th straight week that non-American acts have led the Hot 100.
