A new album featuring the likes of Kate Bush, Annie Lennox and Damon Albarn has just been released. But there is no actual music on the album. "Is This What We Want?" is a protest album which represents the impact on musicians of having AI use their work. As concerns grow about artists rights in the face of AI we ask you what authenticity in music means to you. We also hear a new development in brain cancer treatment and later in the hour we ask you whether you would want to have coffee with your younger self.
