Justin Bieber's run of reaching new chart heights, thanks to his album Purpose, continues, as "Love Yourself" becomes his first No. 1 on Billboard's Adult Pop Songs radio airplay chart (dated March 26, 2016).

Bieber's new breakthrough on Adult Pop Songs could spur further long-term benefits, says Rob Lucas, music director of chart reporter WTSS Buffalo, N.Y. The format (aka, adult top 40, or hot AC) is the "true test of how timeless a song may be." Hits exclusive to the more of-the-moment, youth-focused Pop Songs chart "may not be heard anywhere in five years," he says. With adult pop's greater emphasis on time-tested titles, "the biggest Adult Pop Songs hits will likely be played by numerous formats five years down the road."

Meanwhile, "Love Yourself" co-writer Ed Sheeran makes another trip to the top of Adult Pop Songs. He's earned two No. 1s on the chart as an artist (with songs that he also wrote): "Thinking Out Loud" and "Photograph," each of which ruled for six weeks last year.
