I had the idea a bit ago to make an #ActivityPub version of last.fm/gnu.fm. And I still think it’s a good idea, and would fill a need in the fediverse.
But the more I think about it the more I realize that any solution pretty much *has* to implement the AudioScrobbler protocol, including its oauth1 authentication.
Which gnu.fm already does. So maybe I should start there? But gods DAMN I do not want to deal with that api.
