A production company replaced my score with an AI-generated one two weeks before delivery and paid me a kill fee, this is my account

I have been composing for film and television for eleven years. Two weeks before delivery on a project I had been working on for four months, the production company told me they had decided to use an AI-generated score instead. They paid the kill fee specified in my contract.

They were within their contractual rights. I want to be clear about that. But I want to also be clear about what actually happened because I think a lot of people discussing AI and creative work are doing so theoretically.

I had spent four months on that project. I had watched the rough cuts dozens of times. I had written and rewritten cues to match specific emotional beats. The kill fee covered a fraction of the actual time invested. And the replacement was generated in, as far as I can tell, a few hours.

I am not asking for sympathy. I am asking: is there any version of contracting that protects against this going forward, or is the kill fee clause now essentially a licence for productions to use humans as a backup option until AI is good enough?
