Semi-retired rapper Marshall Mathers (known as Eminem) has filed suit against five companies that allegedly sell ringtones of his music without permission. Cellus USA, FanMobile, Nextones, MyPhoneFiles and MatrixM are all named in the suit which was filed in Detroit, Michigan.
Ringtones are a big business and Mr. Mathers' lawyer says the companies are making hundreds of thousands of dollars a year off of his music. The duo plan to also sue karaoke companies that haven't gotten the necessary copyright agreements.
