Taylor Swift dominates the latest Billboard + Twitter Top Tracks chart, earning the top debut with her cover of Vance Joy's "Riptide," a song from the singer/songwriter's album Dream Your Life Away.

 

She performed the cover during a surprise visit to BBC's Radio 1 (Oct. 9) as a part of its Live Lounge series, where she also performed "Shake It Off." The latter continues to perform well on the Tracks chart, rising 6-3 in its eighth week.

At the top of the chart, Ed Sheeran bounds 45-1 with "Thinking Out Loud," thanks to the debut of its dancetastic official music video on October 7. (In the clip, Sheeran surprisingly ballroom dances with partner Brittany Cherry.) Sheeran also benefits from a tweet from his good friend Swift, who proclaimed the clip is a "masterpiece."

Elsewhere on the chart, Childish Gambino re-enters thanks to the video premiere for his "III. Telegraph Ave." The video, with its shocking surprise ending, bowed on Oct. 10. Lastly, Pharrell Williams notches his seventh hit on the Top Tracks chart after "Gust of Wind" comes in at No. 23 following its Oct. 7 music video debut on Vevo.

Beyonce has a big week on the social charts after releasing a live version of "Flawless (Remix)" on Oct. 6 following her performance of the track in Paris (Sept. 12) during her On the Run tour with Jay Z. In the video, Queen B is joined by Nicki Minaj (who is featured on the remix version of the track), contributing to a sizable amount of online buzz about the performance which causes the track to re-enter the Billboard + Twitter Top Tracks chart at No. 8.

The song's re-entry marks the second-highest point on the Top Tracks chart for Beyonce (second only to the last time it charted back in August). The activity also moves the needle for her on the Social 50, where she goes 28-11 to reach her highest position since the Sept. 20-dated chart (No. 5).

The Social 50 ranks the most popular artists on YouTube, Vevo, Facebook, Twitter, SoundCloud, Wikipedia, Myspace and Instagram. The chart's methodology blends weekly additions of friends/fans/followers along with artist page views, song plays and reactions as measured by music analytics company Next Big Sound.

Beyonce climbs with a 137 percent rise in reactions on Twitter in the week ending Oct. 12, and a 40 percent increase in the number of mentions of her handle on the platform, according to Next Big Sound.

Further down on the Social 50, Lorde re-enters at No. 42 thanks to more than 41,000 mentions of her name on Twitter and a more than 213 percent increase in traffic to her Wikipedia page. The reason for the jump was Lorde’s inclusion on the Oct. 8 episode of Comedy Central's South Park where it was revealed that the 17-year old singer was actually Randy Marsh. Lorde posted a few clips from the episode on her Instagram account, which experienced a 26 percent rise in weekly reactions.

Recapping the Social 50's top 10, Miley Cyrus remains at No. 1 while Selena Gomez ascends 5-2 with a 53 percent rise in weekly Instagram reactions, moving just above Justin Bieber who slides 2-3. One Direction climbs 9-4, moving above Swift (4-5) and Ariana Grande (3-6). Demi Lovato slips a spot (6-7), while 5 Seconds of Summer jump 11-8 over Snoop Dogg, who descends 7-9. Katy Perry goes 8-10 to bring up the rear.
