Two years ago, Universal Music filed a lawsuit claiming that streaming music service Grooveshark carried unauthorized copies of the label’s pre-1972 music catalog on its servers. Universal’s angle was that because of the age of the music and the dating of legislation, DMCA safe harbors are not available to Grooveshark. Yesterday a judge disagreed, and this wasn’t Grooveshark’s only success. The company will now be allowed to push ahead with counterclaims said to be worth tens of millions of dollars.
