Need to populate 'settings' file in json format with the following:

acoustid_api_key from https://acoustid.org/api-key

And for web server and youtube searching capabilities, the following are also needed:

app_secret_key Used to sign cookies. Can be whatever. Something complex. user_agent is whatever you want. I think.

Google developer console under APIs & Auth -> Credentials

google_api_key is the 'API Keys' listing. used for youtube searches

Under the 'OAuth 2.0 client IDs' section: client_id is never what you think it is; the client ID that google expects is not what they provide in the 'client ID' field of their website. You want it in the email format for some ungodly reason. I.E if they provide you with 'abcd123re.apps.googleusercontent.com' you probably want 'abcd123re@developer.gserviceaccount.com redirect_uri is set per client ID
