The MetaBrainz Foundation is seeking a new Executive Director (ED)

This is a copy of the job description at:
https://join.com/companies/metabrainzorg/15986127-executive-director
Please use the above link to apply.

The MetaBrainz Foundation is seeking a new Executive Director (ED) to lead it during a time of great change for how music, data, and code are made, shared and used.

The MetaBrainz Foundation is a non-profit that provides free, open access to data. It is the steward of open source databases and software, including MusicBrainz (a community-maintained open source music metadata encyclopedia that supplies infrastructure to many of the world’s most-used music products and services), and Picard (an open source software application for identifying, tagging, and organizing digital audio recordings). MetaBrainz is supported by its community, sponsors, and by the commercial organizations who rely on what it does.

In collaboration with the Foundation’s Board of Directors, the ED is ultimately responsible for delivering the MetaBrainz mission, guaranteeing the organization’s top priority: the good health of its community. The ED is also in charge of maintaining excellent relationships with industrial partners. Ultimately, you will ensure that MetaBrainz operates with integrity, efficiency and transparency, that it remains in financial good health, and that its small in-house team of developers is supported and managed with sensitivity and professionalism.

Our new ED will be based in Europe. The role involves some travel, as well as virtual meetings in Europe, Asia and the Americas. They will be someone of integrity and good judgement, ideally someone with stature in either the open source or music communities. They will understand the ethical and regulatory requirements of NPOs. They’ll understand the history & mechanics of recorded music and be open to the possibilities and threats from a very rapidly changing technical, commercial and artistic world beyond music.

Tasks

The ED’s primary responsibility is to ensure MetaBrainz fulfils its mission with integrity, transparency, and respect for its community. They will:

Work to keep the MetaBrainz community healthy: welcoming, fair, and constructive.
Represent MetaBrainz, to its community, the public, and the industries it supports, ensuring the Foundation’s strategy and operational activities are communicated appropriately.
Work with the Board to build the Foundation’s strategy and the operational plan to realize it, including budget setting and management, ensuring the organization remains financially stable.
Oversee agreements with commercial partners and suppliers.
Make sure MetaBrainz meets its nonprofit and data-related legal obligations across jurisdictions.
Preempt emerging regulatory and industry changes that could affect the MetaBrainz mission.
Maintain strong, trust-based relationships with current commercial users and sponsors.
Grow relationships with current and prospective partners, encouraging them to support the ecosystem they rely on.
Support and manage the in-house team.

Requirements

Ideally the incoming ED will have:

An excellent understanding of the international music industry.
Experience maintaining healthy, vibrant online communities.
Open source project governance experience.
Knowledge of international copyright frameworks and the commercial framework for music.
Fluency in English (Spanish and other languages a plus).
Experience managing physical and digital events such as community meet-ups, summits, and development intensives.
Knowledge of local and international regulatory frameworks for non-profit organizations.
Experience managing complex software development projects.

C4GT 2025: Integrate Internet Archive Into BrainzPlayer

Hey Everyone 👋!

I am Rayyan Seliya (AKA rayyan_seliya123 on IRC and RayyanSeliya on GitHub), a prefinal year student at Indian Institute of Information Technology Agartala, India, studying Computer Science. I was thrilled to be selected as a contributor in the C4GT (Code For Govt Tech) 2025 program under the MetaBrainz Foundation. My project focused on integrating music streaming from Internet Archive into BrainzPlayer. It was mentored by Kartik Ohri (lucifer on IRC) and Nicolas Pelletier (monkey on IRC).

Project Overview

ListenBrainz has a number of music discovery features that use BrainzPlayer to facilitate track playback. BrainzPlayer (BP) is a custom React component in ListenBrainz that uses multiple data sources to search and play a track. As of now, it supports Spotify, YouTube, Apple Music, SoundCloud, and Funkwhale as music services. It would be useful for BrainzPlayer to support the Internet Archive, which hosts a vast collection of digitized recordings from physical releases of the early 20th century, including 78 RPMs and Cylinder Recordings. Each recording comes with audio streaming and metadata web services that can be used to retrieve metadata automatically and embed a player in ListenBrainz using BrainzPlayer.

We can’t have nice things… because of AI scrapers

In the past few months the MetaBrainz team has been fighting a battle against unscrupulous AI companies ignoring common courtesies (such as robots.txt) and scraping the Internet in order to build up their AI models. Rather than downloading our dataset in one complete download, they insist on loading all of MusicBrainz one page at a time. This of course would take hundreds of years to complete and is utterly pointless. In doing so, they are overloading our servers and preventing legitimate users from accessing our site.

Now the AI scrapers have found ListenBrainz and are hitting a number of our API endpoints for their nefarious data gathering purposes. In order to protect our services from becoming overloaded, we’ve made the following changes:

The /metadata/lookup API endpoints (GET and POST versions) now require the caller to send an Authorization token in order for this endpoint to work.
The ListenBrainz Labs API endpoints for mbid-mapping, mbid-mapping-release and mbid-mapping-explain have been removed. Those were always intended for debugging purposes and will also soon be replaced with a new endpoints for our upcoming improved mapper.
LB Radio will now require users to be logged in to use it (and API endpoint users will need to send the Authorization header). The error message for logged in users is a bit clunky at the moment; we’ll fix this once we’ve finished the work for this year’s Year in Music.

Sorry for these hassles and no-notice changes, but they were required in order to keep our services functioning at an acceptable level.

GSoC 2025: Onboarding Revamp in ListenBrainz Android

Hi everyone,

I’m Hemang Mishra (hemang-mishra on IRC and hemang-mishra on GitHub). I’m currently a pre-final year student at IIIT Jabalpur, India. This summer, I had the opportunity to participate in Google Summer of Code with MetaBrainz. My mentor for the program was Jasjeet Singh (jasje on IRC).

I contributed to ListenBrainz Android, where I worked on revamping the onboarding experience, improving login, adding listen submission apps, integrating Listening Now, and setting up app updates. The journey has been both exciting and full of learning, and I’m truly grateful for this opportunity.

Project Overview

ListenBrainz is a powerful platform that helps track listening history, share music tastes, and build a community around music.

The main goals of my project were:

Revamping onboarding – introducing users to the app’s core features and handling permissions with clear rationale.
Improving login –replacing simple web pages with a custom Compose-based UI, and experimenting with the DOM tree of the web page to automate form submissions and token extraction in the background.
Listen submission apps – prompting users during onboarding to select which apps to collect listens from, preventing unwanted submissions.
Listening Now integration – adding “Listening Now” into BrainzPlayer.
App updates – enabling updates for both Play Store and non-Play Store (F-Droid or sideloaded) releases.

GSoC 2025: MetaBrainz Notification System

Hello, my name is Shaik Junaid (IRC nick fettuccinae and fettuccinae on GitHub). I’m an undergrad computer science student from MGIT, Hyderabad, India. My project focused on adding a central notification system for MetaBrainz.

Project Overview

This project’s idea was suggested to me by mentor @ruaok (AKA mayhem on IRC). I submitted my proposal on the MetaBrainz Forum and got it reviewed by @kartikohri13 (AKA lucifer on IRC), and finally got selected for GSoC 2025 .

A centralized notification management system will various MetaBrainz projects send notifications to users without rewriting boilerplate code. It will also keep users informed about the latest events and new features across projects. This is a goal bigger than the scope of a single GSoC project. To keep it reasonable, my project focused on implementing REST APIs, hosted on metabrainz.org, to manage notifications and user preferences for notifications. Additionally, I integrated the system with ListenBrainz to demonstrate its functionality.

The project spec sheet can be found here.

GSoC 2025: Advanced User Statistics Visualizations

Greetings, Everyone!

I am Granth Bagadia (holycow23 on IRC), an undergraduate Computer Science student at Birla Institute of Technology and Science (BITS), Pilani. This summer, I had the opportunity to participate in Google Summer of Code 2025 with MetaBrainz, where I worked on introducing advanced user statistics visualizations for ListenBrainz.

I was mentored by Ansh Goyal (ansh on IRC), Kartik Ohri (lucifer on IRC), and Nicolas Pelletier (monkey on IRC). This post summarizes my project, its outcomes, and my experience over the course of the program.

Project Overview

ListenBrainz already provided some listening statistics, but these were limited in scope and depth. My project set out to design and implement advanced statistics that could offer users more meaningful insights into their listening habits. Since ListenBrainz is a user-centric platform, the idea was to create features that would let listeners explore their behavior from multiple perspectives. My original proposal focused on introducing a few key statistics.

The core statistics included:

Genre Trends – showing what genres a user listens to at different hours of the day.
Era Statistics – highlighting which musical eras dominate a user’s listening history.
Artist Evolution – tracking how much a user listens to specific artists over time.

GSoC 2025: Importing Listening History Files in Listenbrainz

Hi Everyone!

I am Suvid Singhal (suvid on matrix), an undergraduate Computer Science student at Birla Institute of Technology and Science (BITS), Pilani. I took part in the Google Summer of Code 2025 and have been contributing to Metabrainz Foundation since December 2024. My GSoC project was to develop a file-based listening history importer for ListenBrainz. The project was mentored by Lucifer and Monkey.

Project Overview

Listenbrainz is a platform to track your music habits, discover new music and share your music taste with the community. A feature I missed after creating my ListenBrainz account and connecting Spotify was the ability to see my complete Spotify listening history. My project addresses this gap by allowing users to export their extended streaming history from Spotify and import it into ListenBrainz. Additionally, users can import backups from their old ListenBrainz accounts. With the foundation ready, it will be simpler to add support for more file importers in future. This makes transitioning to Listenbrainz easier.

The importer can be accessed here.

GSoC 2025: Integrate music streaming from Funkwhale & Navidrome

Hey Everyone 👋🏻 !

I am Mohammad Amanullah (AKA m.amanullah7 on IRC and mAmanullah7 on GitHub) final year student at National Institute of Technology Agartala, India and along with that I am a diploma level student at Indian Institute of Technology Madras, India. I was thrilled to be selected as a contributor in the Google Summer of Code (GSoC) 2025 program. My project focused on integrating music streaming from Funkwhale & Navidrome. It was mentored by Lucifer and Monkey.

Let’s start 🙂

Project Overview

ListenBrainz has a number of music discovery features that use BrainzPlayer to facilitate track playback. BrainzPlayer (BP) is a custom React component in ListenBrainz that uses multiple data sources to search and play a track. As of now, it supports Spotify, Youtube, Apple Music and Soundcloud as a music service. It would be useful for BrainzPlayer to support stream music web apps like Navidrome and Funkwhale so that users could stream their private collections as well on ListenBrainz. For those unfamiliar, Funkwhale and Navidrome are self-hosted music servers that implement the Subsonic API, a widely adopted standard for streaming and managing personal music libraries.
