A couple of weeks ago, I started working on a Ruby client for the API, and I'm proud to announce that the very first version was just released! 🥳 https://rubygems.org/gems/listenbrainz It's very bare-bones for the times being (you can only retrieve/submit listens, and a bunch of optional fields aren't included yet), but it's functional and useful enough to exist! I don't know if there are many Ruby developers around, but feedback and contributions are very welcome! <3
