LOS ANGELES, Sept 27: Pop rocker Pink scored her first Billboard No 1 album yesterday, while South Korean singer Psy, who has taken the Internet by storm with his horsey dance moves, landed at No. 1 on the Digital Songs chart with his hit “Gangnam Style.” Psy recently appeared on the “Today” show and “Saturday Night Live” to perform “Gangnam Style” while doing his choppy dance steps that vaguely recall a child riding a stick horse.
