This means you can hear something and say.. you know this is nice, but I would like it more if it were different in this way.
With generative tools you can do that. Personally I really like to listen to music, but I generally dislike the lyrics. I want uplifting songs, maybe about what I am doing right now to motivate me. Well with something like Suno.com.. I can just make one. Or I can work with claude or chatgpt to quickly iterate on some lyrics and edit them to create an even higher fidelity song.
The key here is that I can give a rat's ass if anyone in the world likes or cares about my song.. but I can listen to it while I work. It is exactly what I wanted to listen to or close enough.
