A music industry group on Friday sued Ford Motor Co., General Motors Co. and two electronics companies, demanding that the businesses pay artists and record labels royalties allegedly owed under U.S. copyright law.

In a 21-page class action complaint filed in the U.S. District Court for the District Columbia, the Alliance of Artists and Recording Companies claims Ford and GM, along with Clarion Corp. of America and DENSO International America Inc., failed to abide by the Audio Home Recording Act of 1992. The law requires businesses that manufacture and sell certain audio recording electronics to pay music royalties.
