Backs up a given public Spotify playlists for a given user to text files in both Spotify and human readable formats
Spotify track URI format can be copied and pasted back in to Spotify to restore a playlist to a previous state
( for example if you accidentally deleted a track and didn' t do an immediate Ctrl-Z / Cmd-Z)
For public playlists, \$ SPOTIFY_USER be set in the environment
For private playlists, the user is inferred from the authorized token
$usage_auth_msg
Caveat: due to limitations of the Spotify API, by default works on public playlists.
For private playlists you must export SPOTIFY_PRIVATE = 1 and preferably pre-generate the token in your shell to prevent repeated web authorization pop-ups:
export SPOTIFY_ACCESS_TOKEN = \" \$ ( \" $srcdir /spotify_api_token.sh\" ) \"
