Yahoo China faces legal action from some of the world's top music companies over alleged piracy, the Financial Times reported. In a case led by industry group IFPI, EMI, Sony BMG Music Entertainment, Warner Music and Universal Music are among those suing the US internet portal's China affiliate for US$710,000 in damages. The case is being heard by the same Beijing court that ruled against IFPI in a similar action against Baidu.com last year. IFPI said it had filed the lawsuit because it didn't want to wait for the result of its appeal on the Baidu ruling. The case focuses on Yahoo China's music search service, which links to sites offering music downloads, most of them pirated. Alibaba.com, the online commerce group that owns Yahoo China, said the Baidu ruling meant the music companies had "no case".
