Music giant Sony Music says it has requested the removal of more than 135,000 songs by fraudsters impersonating its artists on streaming services.

The so-called deepfakes were created using generative AI, and targeted some of the company's biggest acts, who include Beyoncé, Queen and Harry Styles

The proliferation of such counterfeits causes "direct commercial harm to legitimate recording artists", Sony said - and deliberately target musicians who are promoting a new album

"In the worst cases, [the deepfakes] potentially damage a release campaign or tarnish the reputation of an artist," said Dennis Kooker, president of Sony's global digital business.

The company says the number of songs generated in this fashion is only increasing as artificial intelligence technology becomes cheaper and easier to access.
