"From the minute the album came out, 'Stressed Out' was raising its hand as a hit record," Fueled by Ramen president Mike Easterlin recently told Billboard. "It was streaming and selling strongly, even as [lead Blurryface single] 'Tear in My Heart' was doing well. I could have never imagined that ['Stressed'] would stay at the top of the Alternative Songs chart for so long or cross to pop so fast, but I think we all felt like we had a hit song."
"Stressed" is the first former Alternative Songs No. 1 to crown Pop Songs in more than two-and-a-half-years, since Lorde's "Royals" in 2013. It's the first by a duo or group to do so in nearly four years, since fun.'s "We Are Young" (featuring Janelle Monae) in 2012.

Also notably, Tyler Joseph, half of the Ohio duo, with Josh Dun, wrote "Stressed" by himself. The song is the first to top Pop Songs penned by a single writer in nearly two years, since Pharrell Williams' self-written "Happy" reigned for four weeks in March-April 2014.
Meanwhile, a pair of high-profile singles debut on the 40 position-deep Pop Songs chart in the top 30: Justin Bieber's "Company" at No. 27 and Meghan Trainor's "No" at No. 28.
With "Company," Bieber follows his first three Pop Songs No. 1s: "What Do You Mean?," "Sorry" and "Love Yourself" (the lattermost of which falls to No. 2 after five weeks on top, his longest command). All four songs are from his former No. 1 Billboard 200 album Purpose.
Trainor, who scored the best new artist Grammy Award last month, unveiled "No" Friday morning (March 4), so it roars onto Pop Songs with less than three full days of plays (with participating iHeartMedia radio stations having spun it hourly that day). The cut, already a No. 1 on the Billboard + Twitter Trending 140, previews her sophomore studio album, Thank You, due May 13. The track additionally arrives on Adult Pop Songs at No. 29.
All charts will update tomorrow (March 8) on Billboard.com.
