Suno AI faces multiple legal challenges over unauthorized use of copyrighted music and artists' likenesses, including lawsuits from Mary J. Blige, Jason Isbell, and a class action by indie artists, while also being found liable in a landmark European copyright case. The company has responded with new licensing agreements, including a deal with BMG, and introduced download limits and streaming-only policies for AI-generated music. A data breach revealed that Suno's AI training involved scraping millions of songs from platforms like YouTube and Genius, further intensifying scrutiny over its data practices.
