Justin Bieber is back on top of the Social 50 chart. The 20-year-old rebounds 7-1 for his record-extending 102nd week atop the chart after releasing a joint track with Cody Simpson.

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.

"Home to Mama," a bare-bones ballad featuring just the two singers and a guitar, debuts at No. 6 on the weekly Billboard + Twitter Top Tracks chart thanks to activity generated on Twitter after its Nov. 11 release. Simpson teased the cover art on Instagram (which has garnered 85,000 likes) and Bieber released the song to his Fahlo account, a new social network centered around celebrities, media and sports. (Scooter Braun, who manages both Bieber and Simpson, is an investor in Fahlo.)

Bieber tops the Social 50 with a 13 percent rise in overall activity after acquiring 650,000 fans across Facebook, Instagram and Twitter. On Twitter, he was mentioned more than 1.8 million times throughout the week ending Nov. 16, and the 2 million likes to his Instagram posts mark a 21 percent boost over the previous week.

As for the rest of the top 10, Ariana Grande (another act managed by Braun) slips 1-3, while Taylor Swift climbs 3-2. Miley Cyrus ascends 5-4, One Direction steps 8-5 and Selena Gomez shifts 4-6. Beyonce jumps up the list (9-7) along with 5 Seconds of Summer (10-8) over Rihanna, who falls 2-9. Demi Lovato rallies 16-10 to anchor the region.

Farther down the chart, Lana Del Rey re-enters at No. 29 with a 70 percent spike in weekly Wikipedia views and a 33 percent rise in Twitter mentions. The reason? In a new cypher in support of the compilation Shady XV (due out Nov. 24), Eminem freestyles that he would "punch Lana Del Rey in the face, like Ray Rice." The controversial lyric garnered a sizable amount of attention in the media, leading to Del Rey’s re-entry.
