Deadmau5 has filed a lawsuit against his former management company, Play Records, claiming tens of millions of dollars in damages over unauthorized remixes and mashups, The Hollywood Reporter reports. According to the statement of claim, Deadmau5 became involved with Play in 2006, when he agreed to make two remixes for its president, Meleny “Melleefresh” Brown, and he then went on to sign music publishing and personal management agreements with the company. A year later, after relocating to London and experiencing some success, he decided to switch over to Three Six Zero Group, another management firm, and, after a dispute, he was forced to buy himself out of his agreement with Brown and cede ownership of his early recordings and compositions — including his first hit, “Faxing Berlin” — to Play.

But while Play was assigned the rights to his music, Deadmau5 is claiming that their settlement agreement expressly detailed how his music could be used. He says that it required his “prior written consent” for any new remix changing the melody and/or lyrics of his tracks, and he also says that “the Settlement Agreement expressly provided that [Deadmau5] did not waive his moral rights with respect to any so-called future remixes — if any were to be made — because by definition any future remix had not been created yet. Thus, [Deadmau5] would have no way of knowing in advance whether they were objectionable or whether he would want his name disassociated with them; i.e. in order to protect his right of paternity to remain anonymous and not be associated with them.”

Now, six years later, Deadmau5 is alleging that Play Records has released remixes and mashups of his early work “not of good technical and commercial quality” and without his approval. He’s suing the company for breach of contract, infringement of moral rights, and trademark claims, as he’s also alleging that Play used his registered designs and marketed his old recordings as new ones.
