I am no fan of Justin Beiber and his hit “Baby,” but it was kinda catchy and kids loved it. Well, he’s been knocked out of the No. 1 spot as the most popular video in YouTube history. Psy’s viral music video hit “Gangnam Style” is now the most popular in YouTube history, having been watched over 805 million times. Psy’s “Gangnam Style” made its YouTube debut July 15 and has over 5.3 million likes and about 320,000 dislikes. Justin Beiber’s “Baby” debuted February 2010 and has only 1.4 million likes and a humongous 3.2 million dislikes.
