Last year they lost their case against Chinese search company, and this year they are at it again with a suit against Alibaba, the company which runs Yahoo China.

Plaintiffs Universal Music Group, Warner Music Group, Sony BMG Music Entertainment, and EMI have filed suit against Alibaba for the equivalent of $710,000 (RMB 5.5 million) in damages. They claim that Yahoo China is infringing on their Copyrights.

The complaint evolves around the music search at Yahoo China allowing users to find and listen to music the vast majority of which is pirated.
