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.
Who’s fault is it that there’s no fair systems one could use (except maybe bandcamp)? Not mine at least, I don’t use Spotify at all. I would not sell my music there if I would be an artist.
I don’t use Spotify, either. And do what you want to do, nobody is forcing your to put your music on Spotify.
