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).
