Swift scores her fourth No. 1, narrowly dethroning Wiz Khalifa's "See You Again." Plus, David Guetta's "Hey Mama" hits the top 10.

Taylor Swift soars to No. 1 on the Billboard Hot 100 with "Bad Blood," featuring Kendrick Lamar, following a full week of tracking after the song's video premiere to kick off the Billboard Music Awards, which aired May 17 on ABC. Winning an extremely tight race, "Blood" displaces Wiz Khalifa's Furious 7 soundtrack hit "See You Again," featuring Charlie Puth, after six weeks on top.

Plus, David Guetta reaches the top 10 with "Hey Mama," featuring Nicki Minaj, Bebe Rexha and Afrojack.?

As we do each Wednesday, let's run down the all the news, good and "Bad," in the top 10 and more on the sales/airplay/streaming-based Hot 100 (dated June 6).

"Blood," released on Big Machine Records and promoted to radio by Republic Records, surges from No. 53 to No. 1 on the Hot 100 following a week of tracking after Swift premiered its celebrity-studded clip to open the BBMAs. The song rockets 26-1 on Digital Songs with 385,000 downloads sold (up 721 percent) in the week ending May 24, according to Nielsen Music. It also vaults onto the Streaming Songs chart at No. 3 with 18.1 million U.S. streams, with 99 percent of its streaming activity from Vevo on YouTube clicks of its official video. On Radio Songs, "Blood" bounds 46-15 with a 109 percent increase to 57 million all-format audience impressions.

Taylor Swift's 'Bad Blood' Video Breaks Vevo Record

The track sweeps the Hot 100's three top gainer awards, for digital sales, streaming and airplay, marking the first song to so triple up since Mark Ronson's "Uptown Funk!," featuring Bruno Mars, earned all three honors on the Jan. 3 chart.

In honor of Swift's new Hot 100 leader, here are 13 (her favorite number) fun facts about the song's coronation:

1. "Blood" is the 1,043rd No. 1 in the Hot 100's history. The chart launched on Aug. 4, 1958.

2. More pertinent to Swift (and fans), it's her fourth Hot 100 No. 1, following "We Are Never Ever Getting Back Together" (three weeks at No. 1, 2012), "Shake It Off" (four, 2014) and "Blank Space" (seven, 2014-15).

3. As "Blood" follows "Shake" and "Space" as the third No. 1 from Swift's blockbuster album 1989, the set is the first to yield three Hot 100 toppers since Adele's 21 in 2011-12: "Rolling in the Deep," "Someone Like You" and "Set Fire to the Rain." (The album version of "Blood" features only Swift, not Lamar, who was added for the single version.)

4. Lamar lands his first Hot 100 No. 1 and second top 10. He'd previously reached No. 8 in 2013 as featured on A$AP Rocky's "F**kin Problems" (also featuring Drake and 2 Chainz).

5. Swift not only tallies her fourth Hot 100 No. 1, but also her 18th top 10. It's her fourth from 1989; in addition to the No. 1s "Shake" and "Space," third single "Style" peaked at No. 6.

6. Swift scores her 10th Digital Songs No. 1. She ties Katy Perry for the second-most leaders on the list. Rihanna leads with 12. Speaking of Perry…

7. … as she's rumored to be the subject of "Bad Blood," perhaps she's the subject of the Hot 100's new top song. Swift's explanation of the lyrical theme (to which Perry may have indirectly responded on Twitter): "For years, I was never sure if we were friends or not," she told Rolling Stone about an unnamed female celebrity. "She would come up to me at awards shows and say something and walk away, and I would think, 'Are we friends, or did she just give me the harshest insult of my life? [Then last year] she did something so horrible. I was like, 'Oh, we're just straight-up enemies.' And it wasn't even about a guy! ... So now I have to avoid her. It's awkward, and I don't like it."

8. The 53-1 jump for "Blood" on the Hot 100 is the greatest to the top since Swift's "Together" hurtled 72-1 in 2012, following its first week of sales (after the song had first charted from early airplay). The record leap to the summit: Kelly Clarkson vaulted 97-1 with "My Life Would Suck Without You" (Feb. 7, 2009).

9. As previously reported, "Blood" blasts onto the Pop Songs chart at No. 13. Only two titles have launched higher in the airplay ranking's 21-year history: Mariah Carey's "Dreamlover" (1993) and Swift's own "Shake," both at No. 12.

10. Also as previously reported, "Blood" broke Vevo's 24-hour worldwide viewing record, with 20.1 million global views in its first day of release.

11. "Bad" news is sometimes good, as Swift's new Hot 100 No. 1 is the 11th song to top the list with the word "bad" in its title. It's the first since Daniel Powter's "Bad Day" in 2006. The first? Jimmy Dean's "Big Bad John" in 1961. Swift's new topper is also the second No. 1 "Bad Blood": Neil Sedaka's different song of the same name reigned in 1975.

12. With her Hot 100 victory, Swift has new fodder for on-stage: The U.S. leg of her 1989 World Tour kicked off last Wednesday (May 20) in Bossier City, La.

13. The race for Billboard's top song of the summer of 2015 just got much more interesting. With "Blood" advancing to No. 1 just before the seasonal tracking period and the return of the annual Songs of the Summer chart, the song will compete from a strong starting spot. We'll find out the winner just after Labor Day.

Taylor Swift Assures a Fan She Is Not Her Mom

As Swift takes over atop the Hot 100, "Again" (1-2), which Khalifa and Puth performed on the BBMAs, tallies its seventh week at No. 1 on both Streaming Songs (22.7 million U.S. streams, down 1 percent) and the subscription services-based On-Demand Songs chart (6.7 million, down 4 percent). And, a strong consolation prize in light of the track's departure from the Hot 100's top perch: "Again" takes over as the new No. 1 on the Radio Songs chart, where it lifts 2-1, up 5 percent to 155 million in all-format audience. On Digital Songs, "Again" dips 1-2 after seven weeks at the apex, with 211,000 downloads sold.

"Again" concurrently leads Billboard's Hot R&B/Hip-Hop Songs and Hot Rap Songs charts for a seventh week each.

Fetty Wap's "Trap Queen" drops to No. 3 on the Hot 100 from its No. 2 high; Walk the Moon's "Shut Up and Dance" holds at its No. 4 Hot 100 peak (and crowns Hot Rock Songs for a ninth week); The Weeknd's "Earned It (Fifty Shades of Grey)" falls from No. 3, its best rank, to No. 5; former 14-week Hot 100 No. 1 "Uptown Funk!" descends 5-6; and Jason Derulo's "Want to Want Me" retreats from its No. 6 high point to No. 7.?

Guetta scores his sixth Hot 100 top 10, as "Hey Mama" rises 11-8 (and leads Hot Dance/Electronic Songs for a sixth week). He'd last reached the top 10 in summer 2012 with the No. 7-peaking "Titanium," featuring Sia. "Mama" is his second top 10 featuring Minaj: "Turn Me On" hit No. 4 earlier in 2012. "Mama" is Minaj's 12th Hot 100 top 10 overall, extending her record among female rappers; Missy Elliott ranks second with nine. Rexha posts her first top 10 and Afrojack his second, following his featured turn (with Ne-Yo and Nayer) on Pitbull's 2011 No. 1 "Give Me Everything."

After Guetta and Minaj performed "Mama" on the BBMAs, and following the release of its official video (May 19), the song sports a 13 percent gain to 112,000 downloads sold, although it slips 5-7 on Digital Songs; hits the Radio Songs top 10 (12-9; 74 million, up 13 percent); and bounds 24-11 on Streaming Songs (7 million, up 50 percent).

Rounding out the Hot 100's top 10, Maroon 5's No. 2-peaking "Sugar" drops 7-9 (while its new single, "This Summer's Gonna Hurt…," charges 67-31) and T-Wayne's "Nasty Freestyle" drops from its No. 9 peak to No. 10.
