Suno, an AI music generator, was breached by a hacker who obtained and disclosed source code showing the company systematically scraped decades of music and podcasts from YouTube, Deezer, Genius, and other platforms to train its model. The breach raises immediate legal questions for Suno given ongoing lawsuits from major labels and artists over unauthorized scraping, and for the broader AI industry about the sourcing of training data without explicit consent from rights holders.
