Louis Tomlinson blasts in at No. 1 on the Billboard + Twitter Top Tracks chart (dated Aug. 5) with “Back to You,” featuring Bebe Rexha and Digital Farm Animals, after the song’s July 21 release. The rollout also included the tune’s official music video, which has raced to more than 13.8 million global plays on YouTube in its first week.

With the song’s coronation, Tomlinson becomes the fifth and final member of One Direction to top the chart as a soloist. Niall Horan, Liam Payne and Harry Styles each reached No. 1 once, with “This Town,” “Strip That Down” and “Sign of the Times,” respectively, while Zayn has clocked five leading titles: “Pillowtalk” (two weeks at No. 1), “It’s You” (two weeks), “Like I Would” (two weeks), “Befour” (one week) and as a featured act on Snakehips’ “Cruel” (one week).

The new single and video helped fuel Tomlinson’s Twitter mentions to 608,000 for the week ending July 23, according to Next Big Sound, a 21 percent surge over the previous frame. On the Social 50 chart (where those Twitter mentions are factored into his ranking), he moves 11-8.

Also within the top five on Billboard + Twitter Top Tracks, Linkin Park’s “Heavy,” featuring Kiiara, re-enters at a new peak of No. 5 following news of the July 20 death of the band’s lead singer, Chester Bennington. In the wake of Bennington’s passing, two additional Linkin Park cuts reach the chart: “Talking to Myself” debuts at No. 10, while “One More Light” bows at No. 15.

The flurry of activity surrounding Bennington extends to all forms of social media, powering Linkin Park to a No. 6 re-entry on the Social 50 chart. Twitter mentions for the band increased by 3,513 percent to 177,000 for the week. Bennington himself, meanwhile, enters the list at No. 12.

Meanwhile, Chance the Rapper collects his 17th entry on Top Tracks as “Big B’s,” featuring Young Thug, debuts at No. 25. The Chicago native released the track on July 14 before replacing it with a “new MASTERED, LOUDER, BIG BASSIER version” as announced in a tweet five days later. The tune -- exclusively available via SoundCloud -- has raced to more than 4.8 million plays on the service worldwide through July 27.

“Big B’s” was released after Chance tweeted “I’m working on the SoundCloud thing” and “@SoundCloud is here to stay” on July 13 and 14, respectively, amid rumors of the streaming service’s impending shutdown.

Chance picks up a 361 percent spike in Twitter mentions to 125,000 for the week. The social boost helps fuel his No. 31 re-entry on the Social 50.
