Swift, U2, Kings of Leon and Paul McCartney are some of the 180 recording artists and labels petitioning Congress to reform the Digital Millennium Copyright Act (D.M.C.A.) In an open letter to Congress, they write that the current online copyright law has allowed YouTube and other sites to “generate huge profits by creating ease of use for consumers to carry almost every recorded song in history in their pocket via a smartphone, while songwriters’ and artists’ earnings continue to diminish.”

The letter, which is being published in The Hill and Politico this week, goes on to call for “sensible reform.” “We ask you to enact sensible reform that balances the interests of creators with the interests of the companies who exploit music for their financial enrichment. It’s only then that consumers will truly benefit.”

YouTube’s parent company, Google, declined to comment Tuesday, but in a statement in April said, “Any claim that the DMCA safe harbors are responsible for a ‘value gap’ for music on YouTube is simply false,” the company said in a statement in April.
