PSY's 'Gangnam Style' Passes Justin Bieber's 'Baby' For YouTube Crown

PSY's 'Gangnam Style' Passes Justin Bieber's 'Baby' For YouTube Crown

Psy tops the Billboard Social 50 for the third week in a row as he continues to showcase his "Gangnam Style" song and its signature dance in the United States. Last week, he appeared on MTV's Video Music Awards broadcast (Sept. 6), which furthered his rise in online standing.

The Social 50 chart ranks the most popular artists on YouTube, Vevo, Facebook, Twitter and MySpace, using a formula that blends weekly additions of friends/fans/followers along with weekly artist page views and weekly song plays.

Surprisingly, performing on stage with the Wanted during the VMA pre-party and again with host Kevin Hart during the actual broadcast later that night wasn't the biggest of Psy's accomplishments during the charting week. Also announced, via a video posted to Psy's official YouTube channel, was a partnership between himself and Justin Bieber's manager, Scooter Braun.

Psy's Schoolboy Records/Universal Republic partnership announcement, along with the continued soaring popularity of the song, helped Psy to remain secured in the No. 1 spot. A 69% increase in weekly overall fanbase acquisition was fueled by 92,000 new Facebook fans, 54,000 new Twitter followers and 95,000 new YouTube subscribers. "Gangnam Style" currently sits above 150 million YouTube views.

Buzz generated by Psy's surprise appearance on "The Ellen DeGeneres Show" this week (on Sept. 10, dancing with the host and guest Britney Spears) may keep him at No. 1 next week.

Elsewhere on the chart, 50 Cent re-enters at No. 13 with a surge in YouTube activity due to the September 4 release of his "Definition of Sexy" music video, a track from his free-to-download "5 (Murder by Numbers)" mixtape. The album is made up of tracks that were originally to be released on his album "Street King Immortal" until 50 Cent decided to change artistic direction, releasing the tracks as a free download on July 6. Overall, the attention brought by the video added up to a 92% increase in overall YouTube plays.

Another YouTube star is beginning to turn heads online, this time one with major label backing. Megan Nicole is a singer-songwriter from Texas with a sizable online following -- over 775,000 Facebook fans, 170,000 Twitter followers and 1.1 million YouTube subscribers. Backed by Bad Boy/Interscope, her single "B-e-a-utiful" is currently on iTunes, while a debut album is in the works. On her fourth straight week on the Social 50, Megan Nicole rises 32-29 as a Q&A video was released to her official YouTube page last week. It garnered over 150,000 views during the charting week, fueling a 58% increase in weekly overall plays. That impact gave Megan 22,000 new YouTube subscribers and 12,000 new Facebook fans.

In the Top 10, Cimorelli jump 19-10 by jumping on the Taylor Swift "We Are Never Ever Getting Back Together" cover bandwagon to help funnel 6 million overall video views to their YouTube channel. Taylor Swift remains steadfast at No. 2 as Rihanna (4-3), Katy Perry (5-4) and Justin Bieber (6-5) increase their standing in the tally. One Direction tumbles (3-6) as Skrillex and Jennifer Lopez remain in their No. 7 and No. 8 spots respectively. Lastly, Lady Gaga elevates (11-9).
