mpdscribble: Listenbrainz implementation actually not supported

[riotbib]

Describe the bug

According to nixos/modules/services/audio/mpdscribble.nix scrobbling to Listenbrainz should be supported. But according to mpdscribble's Issue Tracker this feature is not yet implemented. Even more, I could not get it to run (see log output beneath).

Steps To Reproduce

Steps to reproduce the behavior:

1. Enable mpdscribble module with proposed Listenbrainz configuration
2. Watch it fail

Expected behavior

mpdscribble scrobbles to Listenbrainz.

Additional context

NixOS configuration

{
  services.mpdscribble = {
    enable = true;
    endpoints = {
      "listenbrainz" = {
        passwordFile = "redacted";
        username = "redacted";
      };
    };
  };
}

Log output to systemd

Afaict listenbrainz should support scrobbling with your musicbrainz ID as the username and listenbrainz authorization token as password (inside the passwordFile). What's not supported according to the issue is scrobbling the musicbrainz ID.

Wow, thanks a lot for the fast help! This is very much appreciated.

Using the User token from the profile page of listenbrainz solved it.

I'd open a PR improving documentation for Listenbrainz in the module soon.
