Graham Sutherland / PolynomialAnna's Archive backed up Spotify. They got 99.9% of metadata, and 300TB of music representing 86 million tracks - original 160kbps OGG for tracks with popularity>0, and re-encoded 75kbps for popularity=0. absolutely wild project.
the metadata in particular is a hugely useful data source. MusicBrainz catalogues 5 million unique ISRCs (like ISBNs but for music releases), whereas this archive has a whopping 186 million.
Backing up Spotify
We backed up Spotify (metadata and music files). It’s distributed in bulk torrents (~300TB). 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), with 86 million music files, representing around 99.6% of listens.
