People! Try Yt-dlp, when spotify decide to make Spotify Developer available again, then yt-dlp plugin integration with spotify, still, in anna’s archive i think they will make available if not already the hundreds of TBs of metadata and songs managed to get from Spotify so media preservation and ownership will also be in the digital space

FYI, Tidal is approximately the same price as Spotify and there are several tools floating around on GitHub which will allow you to download high quality flac files from that service.
