Rihanna’s Anti moves back to No. 1 on the Billboard 200 albums chart, collecting its second week at the top. The diva’s set earned another 54,000 equivalent album units in the week ending March 17, according to Nielsen Music.

The Billboard 200 chart ranks the most popular albums of the week in the U.S. based on multi-metric consumption, which includes traditional album sales, track equivalent albums (TEA) and streaming equivalent albums (SEA). The new April 2-dated chart (where Anti is No. 1) will be posted in full to Billboard’s websites on Tuesday, March 22.

Anti is Rihanna’s second No. 1 album (following her previous studio effort, Unapologetic, in 2012) and her first to spend more than one week at No. 1.

Of Anti’s total units for the week, 17,000 were in pure album sales. The rest of its sum -- a sizable 69 percent -- was comprised of TEA and SEA units, thanks to the popularity of its tracks (like the smash single “Work,” which has spent four weeks at No. 1 on the Billboard Hot 100 chart).

Adele’s former No. 1 album, 25, holds at No. 2 on the new Billboard 200 with 51,000 units (down 15 percent), while Justin Bieber’s Purpose climbs 5-3 with 48,000 units (down 9 percent).

Joey + Rory’s Hymns returns to its peak position, as the country/Christian effort steps 6-4 with just over 44,000 units (down 1 percent). Nearly all of its units were powered by traditional album sales (44,000 copies sold in the week, down less than 1 percent), which pushes the title from No. 3 to its first week at No. 1 on the Top Album Sales chart. The list ranks the top selling albums of the week, based on pure album sales.

With the ascent, Hymns becomes only the sixth Christian or gospel album to be the best selling album of the week. It follows Lecrae's Anomaly (2014), Chris Tomlin's Burning Lights (2013), TobyMac'Eye on It (2012), LeAnn RimesYou Light Up My Life -- Inspirational Songs (1997) and Bob Carlisle's Butterfly Kisses (Shades of Grace) (1997).

The No. 1 rise for Hymns follows the death of the duo’s Joey Feek, who died from cancer on March 4. The album was recorded last year, as Feek was undergoing chemotherapy and radiation treatments.  

Notably, Hymns logs the third-smallest weekly sales figure for a No. 1 on the Top Album Sales chart since Nielsen Music began electronically tracking music purchases in 1991. It trails only the No. 1 debut of Amos Lee’s Mission Bell (40,000 in 2011) and the Descendants TV soundtrack (30,000 in 2015).

Back on the new Billboard 200, Kendrick Lamar’s Untitled Unmastered falls from No. 1 to No. 5 in its second chart week, moving 38,000 units (down 78 percent).

Rock band Killswitch Engage starts at No. 6 with Incarnate (35,000 units, with 33,000 in pure album sales). It’s the third top 10 effort for the group, and their highest charting set yet, following a pair of No. 7-peaking albums in 2013 and 2009 (Disarm the Descent and its self-titled album, respectively).

Chris Stapleton’s Traveller is a non-mover at No. 7 with 34,000 units (down 13 percent), while Twenty One PilotsBlurryface is also steady at No. 8 (33,000 units; down 4 percent). Kevin GatesIslah rises one rung to No. 9 with 30,000 units (up less than 1 percent).

Hip-hop trio Flatbush Zombies rounds out the top 10, as the act’s debut full-length album, 3001: A Laced Odyssey, beams in at No. 10 with 28,000 units (24,000 in pure album sales). The set recently notched a top 40 hit on the Billboard + Twitter Top Tracks chart with “Bounce,” which debuted and peaked at No. 32 in February.
