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.
That’s exactly what I was wondering too.
Acquiring high quality music is already easy enough in most cases.
What I am interested in is the metadata. Accurate tagging of all my files is of high interest.
