The music giant is suing social-networking site Hi5, video advertising start-up VideoEgg, and 10 unnamed defendants for allegedly infringing on the copyrights of those and hundreds of other pop throwbacks.

The lawsuit alleges that Hi5 users have uploaded and disseminated hundreds of music videos the company owns rights to. VideoEgg is on the hook because it’s a former partner of Hi5, and those allegedly infringing videos were uploaded to its servers.
