Sony, Warner join in on Grooveshark lawsuit
Sony Music and Warner Music have now joined the copyright infringement lawsuit Universal Music started against online music service Grooveshark. The lawsuit was first filed in November and alleges that Grooveshark execs uploaded copies of songs to which they didn't have rights and thus broke the DMCA. The lawsuit was also amended with a detail that claims Grooveshark knew it needed a license for the material it offers, according to the Wall Street Journal.
EMI Group licensed its songs to Grooveshark after settling its own lawsuit against the service. Grooveshark is a streaming service, and lets users listen to songs for free through their browsers. It uses ads to generate revenue.
Grooveshark maintains it will "aggressively" defend its rights in court and already respects the intellectual property of all artists.
