The archive uses torrents for distribution, prioritizes tracks by popularity, stores files in OGG Vorbis (160kbit/s for popular tracks) and OGG Opus (75kbit/s for unpopular tracks), and includes the world's largest publicly available music metadata database with 186 million unique ISRCs. The metadata is structured in SQLite databases covering artists, albums, tracks, playlists, audio features, and file information, making it the first fully open music preservation archive that can be easily mirrored. ## Full article daily.dev links to this article rather than hosting it.
