This is the code repository for Powertools for Spotify.
It is a motley collection of tools to examine and edit your Spotify collection.
The hardcoded OAUTH_CLIENT_ID in index.html is my own Spotify API (public) key. I have it configured so that the only allowed redirect_uri is the hosted instance linked above. Thus, to test your changes, you'll want to create your own Client ID, enable your own Redirect URI (for example, http://localhost:8000/), then update OAUTH_CLIENT_ID.
