usage_description="
Returns Spotify API output for a given public playlist

Playlist argument can be a playlist name (or partial string match) or a playlist ID (get this from spotify_playlists.sh)

\$SPOTIFY_PLAYLIST can be used from environment if no first argument is given

$usage_auth_msg

Caveat: limited to 50 public playlists due to Spotify API, must specify OFFSET=50 to get next 50.
        This script does not iterate each page automatically because the output would be nonsensical
        multiple json outputs so you must iterate yourself and process each json result in turn
        For an example of how to do this and process multiple paged requests see spotify_playlist_tracks.sh

For private playlists you must specify \$SPOTIFY_PRIVATE=1 before generating the \$SPOTIFY_ACCESS_TOKEN:

export SPOTIFY_PRIVATE=1

export SPOTIFY_ACCESS_TOKEN=\"\$('$srcdir/spotify_api_token_interactive.sh')\"
