Smoodify uses spotify's personalization algorithm to recommend you the songs you might like, and also allows you to create playlists based on your current mood.
To Use:
-> Create a spotify developer account and get your client_id, client_secret, and redirect ui
-> Create your auth code by converting cliend_id:client_secret to a base 64 format and save it in a variable called auth_code
-> store your auth_code, client_id, and redirect_ui in a .env file
-> Do npm start and your're good to go!
