Today, I went to an event on AI and music. One of the presenters was Drew Silverstein from Amper Music, a startup that uses AI to create original music (e.g. music for commercials). I was impressed by their demo where they select inputs such as "genre", "mood", and "time", and then played a beautiful, structured music. Drew mentioned that unlike other AI tasks (classification, prediction), the metric of "right" or "wrong" is ambiguous for music creation, because how we perceive music is subjective. Their demo showed that while tasks like music creation is different from traditional AI tasks, statistics and math can contribute and assist in creative process.
