"Like" is the second single from Mars' third LP, 24K Magic. The title cut hit No. 5 on Pop Songs in December.
Here's a recap of Mars' eight Pop Songs No. 1s:
"Nothin' On You" (B.o.B feat. Mars), one week, May 22, 2010
"Just the Way You Are," three weeks beginning Oct. 30, 2010
"Grenade," five, Feb. 5, 2011
"It Will Rain," one, Feb. 4, 2012
"Locked Out of Heaven," five, Dec. 29, 2012
"When I Was Your Man," three, April 13, 2013
"Uptown Funk!," (Mark Ronson feat. Mars), six, Feb. 7, 2015
"That's What I Like," one (to date), May 6, 2017
Timberlake tallied his eighth Pop Songs No. 1 with "Can't Stop the Feeling!," which led for three weeks beginning June 18, 2016. He first reigned as a soloist with "Rock Your Body," for four weeks in 2003. Overall, he's made 10 trips to No. 1 on Pop Songs, having first led with *NSYNC on "Bye Bye Bye," for 10 weeks, and "It's Gonna Be Me," for two, both in 2000.
Mars, meanwhile, has topped Pop Songs nine times total, including his output as a writer: he co-penned Flo Rida's two-week 2009 No. 1 "Right Round," before ruling as an artist. And, he's co-produced and co-written all eight of his Pop Songs No. 1s as a performer. Timberlake has also co-written all eight of his Pop Songs leaders and, like Mars, co-authored one for another act: The Black Eyed Peas' "Where Is the Love?," a seven-week No. 1 in 2003; he's co-produced six of his eight No. 1s.
Mars' "Like" bullets at No. 3 on the all-format airplay, streaming and sales-based Billboard Hot 100, after four weeks at its No. 2 high. It's up 6 percent to 160 million in all-format airplay audience, its best weekly total, in the week ending April 23.
"Like" additionally leads Billboard's Hot R&B Songs chart for a 10th week, after topping Hot R&B/Hip-Hop Songs for four, marking Mars' first No. 1 on each survey. 24K Magic has ruled Top R&B/Hip-Hop Albums (where it's also his first No. 1) for eight weeks and ranked in the top three each week since its Dec. 10 debut at the summit.
