Google DeepMind's music-AI licensing/opt-out posture stated on the record

In an interview for a feature on AI-music copyright tensions, Jeff Chang, Director of Product Management at Google DeepMind, said Flow Music (built on Google's Lyria models) trains only on music Google has legal rights to via terms of service and partner agreements, that users have an opt-out toggle for their data being used in training, and that DeepMind has done "a lot of work behind the scenes" to prevent outputs from regurgitating existing works.
