Anna's Archive 'backed up' Spotify's massive catalogue to preserve online music

Spotify's library was scraped and released by pirate activists Anna's Archive just two weeks after the streaming giant released its "largest Wrapped ever."

The unprecedented data grab of nearly 300 terabytes was announced by the website in a Dec. 20 blog post. The archive says it obtained metadata for 99.9 percent of Spotify's 256 million tracks and audio files for 86 million pieces of music, or a library that represents about 99.6 percent of listens on the platform.

"It’s the world’s first 'preservation archive' for music which is fully open (meaning it can easily be mirrored by anyone with enough disk space)," said Anna's Archive. "With your help, humanity’s musical heritage will be forever protected from destruction by natural disasters, wars, budget cuts, and other catastrophes."

Anna's Archive made the metadata library immediately available for public download, and says it will release the rest of the scrape in stages, including music files and album artwork. It also released an expansive breakdown of the metadata including stream count, genre, and popularity analysis.

"An investigation into unauthorized access identified that a third party scraped public metadata and used illicit tactics to circumvent DRM to access some of the platform’s audio files. We are actively investigating the incident," Spotify wrote in an initial statement to Android Authority. As of Dec. 22, Spotify said it has "identified and disabled the nefarious user accounts that engaged in unlawful scraping." The streaming platform also said it is implementing new safeguards against further copyright attacks to combat piracy.

Anna's Archive, an open source search engine that directs users to pirated, paid, or paywalled content like books and articles, has become a bane of copyright holders across the internet. Last month, Google removed more than 749 million search result links that directed to Anna's Archive, a vast majority of the 784 million link removal requests the company received. According to reporting by TorrentFreak, Anna's Archive URLs (annas-archive.se, annas-archive.org, and annas-archive.li) face the highest amount of Google takedown requests.
