The collab with Charlie Puth matches the 12-week reigns of two prior smashes. Plus, Skrillex & Diplo, with Justin Bieber, and Rachel Platten hit the top 10.

Wiz Khalifa's "See You Again," featuring Charlie Puth, matches an historic mark, as it leads the Billboard Hot 100 for a 12th week. With its latest frame on top, it ties the record for the longest run at No. 1 ever for a rap single.

Plus, OMI's "Cheerleader" takes over as the top-selling song in the country, Taylor Swift's "Bad Blood," featuring Kendrick Lamar, is the new most-heard song, and two singles reach the Hot 100's top 10, by Skrillex & Diplo, with Justin Bieber, and Rachel Platten.

As we do each week, let's run down the top 10 and more on the sales/airplay/streaming-based Hot 100 (dated July 18).

"Again," from the smash film Furious 7 and released on Atlantic Records and promoted to radio by Roadrunner Promotions, equals the longest run at No. 1 ever for a rap hit (defined as a title that has appeared on Hot Rap Songs). Here's an updated look at the rap No. 1s that have ruled the Hot 100 the longest:

"Again" holds the No. 1 spot on the Hot 100 despite no longer leading any of the chart's component lists. Still, its total activity is enough to keep it at the summit: It drops 1-2 on the Radio Songs chart, after six weeks on top, with 152 million in all-format audience (down 7 percent), according to Nielsen Music; 2-3 on Streaming Songs (14.8 million U.S. streams, down 4 percent), after eight weeks in charge; and 7-10 on Digital Songs (81,000 downloads sold, down 18 percent, in the week ending July 5), which it led for seven weeks.

("Again" is the first song to top the Hot 100 without leading at least one of the chart's three component tallies -- Radio Songs, Streaming Songs and Digital Songs -- since MAGIC!'s "Rude" did so the last two weeks of its six-week Hot 100 command last August.)

'See You Again' Still the No. 1 Song of the Summer ... So Far

"Again" additionally leads Billboard's Hot R&B/Hip-Hop Songs and Hot Rap Songs charts for a 13th week each and the Songs of the Summer chart for a sixth week. Roughly a third of the way through the season, "Again" still dominates the race for top song of the summer so far: it's ruled Songs of the Summer each week since the chart made its annual return after Memorial Day.

Can "Again" claim the record all to itself with a 13th week at No. 1 on the Hot 100 next week?

It faces a serious challenge from OMI's "Cheerleader": it pushes 3-2 and trails "Again" by a narrow margin this week (with "Again" down by 8 percent in overall activity and "Cheerleader" up by 8 percent). The reggae artist's breakthrough hit crowns Digital Songs (2-1) despite a 3 percent decrease to 170,000. It holds at No. 4 on Streaming Songs, although up by 19 percent to 12.6 million, and climbs 8-7 on Radio Songs (94 million, up 13 percent). The song also passes 1 million (1.1 million) in downloads sales to-date.

"Cheerleader" marks a further celebration, for Ultra Records (which shares label credit on the song with Columbia Records): by reaching No. 2, the song ties for the highest-charting hit ever released on the label. Ultra first reached No. 2 with Pitbull's "I Know You Want Me (Calle Ocho)" in 2009.

Also in play for No. 1 on the Hot 100 going forward: Silento surges 7-3 with his debut hit "Watch Me" (up 42 percent). The 17-year-old rapper's first top 10, powered by its viral success, bumps 3-2 on Streaming Songs (19 million, up 54 percent) following the June 25 premiere of its official video. It also zooms 8-3 on Digital Songs (127,000, up 30 percent), winning the Hot 100's top Streaming and Digital Gainer awards. It additionally enters Radio Songs at No. 40 with an 18 percent gain to 34 million.

After five weeks at No. 2, Taylor Swift's "Bad Blood" drops 2-4 on the Hot 100. (It notched a week at No. 1, interrupting the reign of "Again" on the chart dated June 6.) Still, new honors for the track: "Blood" rises 2-1 on Radio Songs (155 million, up 2 percent), becoming Swift's fifth No. 1 on the chart. Swift previously led Radio Songs with prior 1989 singles "Blank Space" (for six weeks) and "Shake It Off" (four) and with "I Knew You Were Trouble." (four) in 2013 and "You Belong With Me" (two) in 2009.

Rounding out the Hot 100's top five, Fetty Wap's "Trap Queen" drops 4-5 after reaching No. 2. It logs a fifth week at No. 1 on Streaming Songs (19.6 million, up 1 percent) and a seventh week atop the subscription services-based On-Demand Songs chart (5.5 million, essentially even from last week).

At four weeks on the Hot 100, it's easily the youngest song in the top 10; "Blood" is next at 10 weeks old. "Face" flies 5-2 on Digital Songs (128,000, up 10 percent); leaps 10-6 on Radio Songs (96 million, up 24 percent); and enters the Streaming Songs top 10 (9.2 million, up 33 percent).

Walk the Moon's "Shut Up and Dance" descends 5-7 on the Hot 100 after peaking at No. 4. It leads the Hot Rock Songs chart for a 15th week.

New to the Hot 100's top 10, Skrillex & Diplo's "Where Are U Now," with Justin Bieber, rockets 17-8 following the June 29 arrival of its official video. It roars 15-5 on Streaming Songs (10.7 million, up 66 percent) and rises 13-12 on Digital Songs (78,000, up 8 percent) and 19-17 on Radio Songs (59 million, up 6 percent). Skrillex and Diplo each notch their first Hot 100 top 10 as artists (Diplo made four prior top 10 trips counting his writer and producer credits), while Bieber scores his sixth Hot 100 top 10. It's his first since "Beauty and a Beat," featuring Nicki Minaj, which rose to No. 5 in January 2013.

"Where" also takes over atop Hot Dance/Electronic Songs. It dethrones David Guetta's "Hey Mama" (featuring Minaj, Bebe Rexha and Afrojack), which rebounds 10-9 on the Hot 100, after reaching No. 8. It led Hot Dance/Electronic Songs for 11 weeks.

Rachel Platten Talks 'Fight Song' & Performing with Taylor Swift: 'She Radiates Love and Kindness'

Rachel Platten notches the week's other new Hot 100 top 10 as "Fight Song" flies 14-10. The empowerment anthem from the Boston area-raised pop singer/songwriter holds at No. 4 on Digital Songs (125,000, down 8 percent) and climbs 18-13 on Radio Songs (65 million, up 15 percent) and 37-28 on Streaming Songs (4.7 million, up 31 percent). It passes 1 million (1.1 million) in sales to-date.

Platten becomes the second woman this year to send a first Hot 100 entry into the top 10, following Natalie La Rose's "Somebody," featuring Jeremih, which reached No. 10 in April.

"I've been trying to do this for a long time, and I got rejected a lot," Platten recently told Billboard. "I wrote 'Fight Song' at a real low moment of feeling like, 'Should I quit?' There weren't a lot of signs to keep going. But, something in me, this tiny, little, crazy voice, would not let me quit."

In highlights just below the Hot 100's top 10, Fifth Harmony's "Worth It," featuring Kid Ink, rebounds from No. 15 to No. 14, returning to its best rank; Rihanna reaches a new peak with "B**** Better Have My Money," which vaults 28-15 following the July 1 release of its official video (after previously peaking at No. 17 in early May); and, The Weeknd likewise reaches a new highpoint with "The Hills" (23-19).
