I’m looking for a 1960s-70s science fiction short story anthology on fine arts. I only remember the summary of 2 of the stories.
One was of composer who wrote commercial music by hand while most wrote using AI so they could “compose” music faster and he was having trouble getting his music sold.
Another was of a community in which a psychologically troubled person lived and he did not know that the people around him were all actors creating an environment to help “cure” him
