Leaked source code from AI music generator Suno reveals the company scraped millions of songs from YouTube Music, Deezer, and Genius. The leak, reported on July 15, 2026, substantiates copyright infringement claims filed by Sony Music Entertainment and Universal Music Group.
The evidence shows Suno ingested over 2 million music clips to train its models. This data includes hundreds of thousands of hours of copyrighted audio. Sony and UMG are now seeking to expand their lawsuit to over $9 billion in potential damages.
Suno argues that training AI on publicly available internet files constitutes fair use. The company confirmed the security breach but stated the exposed code was outdated.
