Folk singer Emily Portman, who found a counterfeit potentially AI-generated album purporting to be created by her online, poses for a photograph in Sheffield, northern England, on November 21, 2025. British folk musician Emily Portman was taken by surprise in July when she received a message from a fan congratulating her on her new album even though she hadn't released one since 2022. That's when she discovered "Orca" in her Spotify and Apple Music catalogues. The titles of the songs were like something she might have created herself, but "very quickly I recognised it was AI-produced music", she said. (Photo by Oli SCARFF / AFP via Getty Images)
