Spotify's Music Catalog Leaked in Massive Data Breach

Anna's Archive backed up 300 terabytes of Spotify data, preserving metadata for 256 million tracks and audio for 86 million, covering 99.6% of Spotify listens.

  • Anna’s Archive announced on December 20, 2025 that it backed up 86 million music files representing 99.6% of all Spotify listens and released a 300TB archive via bulk torrents.
  • Anna’s Archive framed the upload as preservation, arguing Spotify is a single point of failure and calling it the world’s first comprehensive open music preservation archive for archivists.
  • The archive’s metadata database contains 256 million tracks and 186 million unique ISRCs, plus 6.6 million playlists with 1.7 billion playlist tracks, preserving files in OGG Vorbis and OGG Opus.
  • At the same per-track penalty, theoretical exposure could reach $19,400,000,000,000, and the Internet Archive settled for $621 million, greatly increasing Anna’s Archive's legal risks.
  • Most musicians make under $5,000 yearly, and Spotify says it will tighten API access and anti-scraping measures as torrents create decentralized, hard-to-shut-down backups.
