How does music shape the social and cultural fabric of Europe? What can patterns of music consumption reveal about policies, inclusion, and everyday life? Music is not only a mirror of culture, but also a living indicator of how communities evolve and interact. Today, the growing availability of music-related data opens new perspectives to understand the social value of music and its potential to build fairer and more sustainable ecosystems. When used responsibly, data can help policymakers, researchers, and professionals identify gaps, measure impact, and support better decision-making. By turning open data into collective knowledge, projects like OpenMusE aim to bring more transparency, visibility, and fairness to Europe’s music landscape, bridging analysis, policy, and creativity. Can data really become a common good for music? And how can openness drive the next phase of Europe’s cultural development?
