Returns track URIs for the given Spotify public playlist
Playlist argument can be a playlist name ( a regex which will return the first matching playlist)
or a playlist ID ( get this from spotify_playlists.sh)
\$ SPOTIFY_PLAYLIST can be used from environment if no first argument is given
Spotify track URIs can be used:
- as backups to restore a playlist' s contents
- copied to new playlists
- set to Liked ( spotify_set_track_uris_to_liked.sh)
Requires \$ SPOTIFY_ID and \$ SPOTIFY_SECRET to be defined in the environment
Caveat: due to limitations of the Spotify API, this by default only works for public playlists. For private playlists you must get an interactively authorized access token like so:
export SPOTIFY_ACCESS_TOKEN = \" \$ ( \" $srcdir /spotify_api_token_interactive.sh\" ) \"
