Suno AI has faced multiple legal and ethical challenges over its use of copyrighted music for training AI models, including lawsuits from artists like Jason Isbell and SOCAN, and a class action involving indie musicians. In response, Suno has entered licensing agreements with major labels such as Warner Music, BMG, and Believe, and introduced new policies limiting AI music downloads and offering vinyl pressings for generated tracks. The company also reversed its stance on distribution after initially rejecting TuneCore, and pulled a Mary J. Blige ad after discovering it lacked her consent.
