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.
It can’t, but I’m sure that wouldn’t stop Spotify from raising a stink if they see it being bulk imported. I’d imagine this would be similar to OpenStreetMaps and Google Maps; they probably could scrape and bulk import missing info, but they restrict it to licensed sources and user edits to limit liability and enforce quality.
In cartography the expression of the uncopyrightable data is itself copyrighted (e.g. colors used, thickness of ligns) so maybe certain data fields are owned by Spotify (e.g. genre, description, history, song notes)
