Anna's Archive has backed up and preserved Spotify's music and metadata, creating a ‘preservation archive’ for music that is openly accessible. The archive includes approximately 300TB of data with 256 million tracks, 186 million unique ISRCs, and 86 million music files, capturing around 99.6% of all music listened to on Spotify. This effort is a response to existing music backup efforts' focus on popular artists and high-quality audio files, as well as the lack of a comprehensive music torrent list that represents all music ever produced.
