That 2 hour mix was created in an extremely short amount of time. Limited by the fact suno and udio don't have API's. I've done tonnes of work using replicate.com musicGen A.I that I threw in the bin once I heard udio & suno... once we get API access... there will be new genre's of music and hyper media beyond what we can consider normal music now.
There is some scope for prompt engineering with text-to-* media generators... combined with automation. Machine listening and categorization: For example a network of virtual listeners able to refine and generate new work before a human hears it... think music agent systems by Nick Collins on steroids.
