The late Whitney Houston's videos are in high-demand on both YouTube and Vevo, as her play count increased by 4,523% last week, according to Next Big Sound. She went from 868,000 plays to 40.2 million in the week ending Feb. 20.
In turn, the diva -- who died on Feb. 12 -- moves from No. 12 to No. 2 on Billboard's Social 50 chart. The tally ranks the most popular artists on YouTube, Vevo, Facebook, Twitter, MySpace and iLike, using a formula that blends weekly additions of friends/fans/followers along with weekly artist page views and weekly song plays.
Elsewhere on the list, many acts that were featured on the Feb. 12 Grammy Awards see a boost, as Katy Perry (13-9), Lady Gaga (15-13), Lil Wayne (22-14), Bruno Mars (24-15) and Taylor Swift (23-16) all make gains. Re-entering this week are Grammy performers Coldplay (No. 33) and Deadmau5 (No. 40).
Holding court at No. 1 again this week is Adele, who saw a 116% jump in Vevo/YouTube plays and a 62% leap in Facebook fans. As for the rest of the top 10, Nicki Minaj moves 2-3, Rihanna slips 3-4 and Michael Jackson climbs 8-5. Justin Bieber falls 4-6, David Guetta stays put at No. 7 and Shakira descends 6-8. Rounding out the top 10 is Chris Brown, who moves down a slot to No. 10.
The biggest positional fall on the list belongs to Madonna, who runs from No. 5 to No. 31. She was down 23% in Facebook fans and had a steep 80% drop in YouTube views to her official channel. None of this should be too surprising, as her positioning on the tally in the past two weeks came as a result from hype surrounding her Feb. 12 Super Bowl halftime show performance. With the Super Bowl firmly in the rear view mirror, there isn't enough social buzz to keep the diva in the top 10.
