Bad news for fans of free streaming music websites: Universal Music has initiated a lawsuit against popular streaming site Grooveshark, claiming the company has uploaded upwards of 100,000 songs without permission.

The suit in question even goes as far as naming individuals in Grooveshark who Universal claim are responsible for the illegally uploading content, including Grooveshark CEO Samuel Tarantino, who is allegedly personally responsible for uploading 1,791 songs from the Universal catalogue.

Universal is asking for a $150,000 payoff PER INFRINGEMENT from Grooveshark, which could lead to a potential payout of $15 billion.
