"The government's proposal would hand the life's work of the country's musicians to AI companies, for free, letting those companies exploit musicians' work to outcompete them,” he said.
Under the proposals, an exemption to copyright would be created for training AI, so tech firms would not need a licence to use copyrighted material, and creators would need to opt out to prevent their work from being used.
Others have warned that government proposals to change UK copyright law to allow AI models to be more easily trained on copyrighted material would cause untold damage to the creative sector, and see human artists replaced in the long term.
Critics of the proposals have argued that it fails to reimburse artists for AI recreating and copying their work, would stifle creativity, and that the proposed opt-out scheme places an unnecessary burden on artists.
Dan Conway, chief executive of the Publishers Association, the trade organisation representing book, journal and electronic publishers in the UK, said: "The extraordinary strength of support shown in recent weeks for copyright and our world-class creative industries is something the Government ignores at its peril.
