Don't know about you guys, but I always add album as new playlist. I appreciate radio but listening to a whole album has it's own charm.
So the playlists (not necessarily the tracks) is sort of a backlog / history I want to safe keep somewhere outside of Spotify.
And it seems the reason we can't export delimited text, XML or similar is purely political. It's certainly nowhere to be found in the official clients. I've looked through the APIs (which seems to be improving), nothing stands out that would support such a feature.
Attached at the bottom is the source code for a program that can parse and print the "playlist.bnk" file. I assumed the format is not publicly known (though not hard to guess). Can we have specifications please?
It needs to be improved upon, it doesn't quite catch all of my playlists.
For *nix "playlist.bnk" is located in ~/.config/spotify/Users/name/playlist.bnk
