Allows you to whitelist Spotify users for your collaborative playlists.
Once the repository is cloned, read and follow the secrets.format.py file. When you have your secrets.py configured run the main.py file. You will then be prompted to insert a playlist URI, the program will then filter your playlist's tracks and save a backup pickle file.
Note: The owner of the playlist needs to use their account to create the app credentials. Spotify doesn't allow you to edit other people's collabs through the API.
