I've always wanted a local script that would back up all the playlists automatically (instead of having to copy-paste things manually like you can do now), and be able to run it whenever you want to back it up. I don't even care about restoring, I just want to keep my playlist info in any plaintext format so that if Spotify disappears or I leave, I can still have the playlist info and rebuild them elsewhere.

Does this exist, or would I have to hack my own script together?
