There are some options I wasn't 100% sure of, that someone who knows beets better might be able to clarify.
Not all plugins are tested, for example I do not have a Spotify account.
That said, with what is currently enabled, someone should be able to copy the file to the configuration directory and have a working config file.
I've uploaded it to:
