A digital rights group has claimed to have harvested millions of songs from the popular streaming service and is preparing to release them publicly.
Industry experts noted the apparent leak could aid artificial intelligence firms looking for data to train their technology.
A group known as Annaâs Archive said it had scraped 86 million audio tracks from the platform and 256 million entries of associated data such as performer and album names. The company, which hosts more than 100 million tracks, confirmed that the breach did not constitute its full inventory.
âWe have identified and deactivated the malicious user accounts that were involved in illegal scraping,â said a company representative.
The Swedish company, which has more than 700 million users worldwide, added that an investigation into unauthorised access found a external actor collected public metadata and used questionable methods to bypass DRM protections.
The streaming service does not think the audio acquired by Annaâs Archive has been made public yet. Annaâs Archive, which is recognized for offering links to copyright-infringing books, said in a blog it wanted to create a âpreservation archiveâ for music.
They claimed the audio files accounted for 99.6% of all music listened to by its listeners and would be shared via âpeer-to-peer networksâ, a method of sharing large digital files online.
âNaturally the service doesnât have all the music in the world, but itâs a fantastic beginning,â commented Annaâs Archive, which frames its purpose as âpreserving humanityâs knowledge and cultureâ.
Ed Newton-Rex for defending artistsâ rights, said the leaked music would likely be utilized for developing artificial intelligence systems.
âTraining on illegally sourced material is sadly widespread in the AI industry, so this stolen music is almost certain to be used training AI models,â he stated.
The Annaâs Archive site alludes to LibGen, a vast online archive of copyrighted books that has reportedly been used by the parent company of Facebook to develop its systems.
The co-founder of an artificial intelligence company wrote on the professional network that members of the public could in theory âbuild their own private free version of the serviceâ. He added it could also allow tech companies to âtrain on contemporary music at scaleâ.
Intellectual property law has become a battleground between artists, writers and creatives on one side and AI companies on the other.
Across Britain, artists and writers have protested against a government suggestion to allow AI companies utilize copyright-protected work without permission unless the rights holder signals. Virtually every respondent to a government consultation on the proposal has supported artistsâ apprehensions.
The secretary of state for technology, research and technology told parliament this month there was âlittle consensusâ on the matter, noting that ministers would âuse the time to get this rightâ. The government has committed to make policy proposals on AI and copyright by March 2025.
