Important: Login will not work unless your Spotify email is whitelisted in the console
If you're a friend of mine who wants to mess around with the app, let me know and I can enable it for your Spotify account
You can also open an issue on the GitHub page if you just stumbled upon this
If there's enough user demand, I can look into opening this up for general usage, but doing this for Spotify apps isn't as easy as it once was
The app doesn't store any user information - login is only required so tracks can be searched for using the Spotify API, and if you want to save any created Playlists
