Last month, award-winning singer Emily Portman got a message from a fan praising her new album and saying "English folk music is in good hands".
That would normally be a compliment, but the Sheffield-based artist was puzzled.
So she followed a link the fan had posted and was taken to what appeared to be her latest release. "But I didn't recognise it because I hadn't released a new album," Portman says.
"I clicked through and discovered an album online everywhere - on Spotify and iTunes and all the online platforms.
"It was called Orca, and it was music that was evidently AI-generated, but it had been cleverly trained, I think, on me."
