There is absolutely some form of creation there. The most basic models now are just prompts but somebody has to prompt them, there is a human being there prompting the song and then deciding to share it (a form of curation).

I'd imagine these will get more and more granular to where you're not just prompting but you are gradually building up songs and at that point I'd be surprised if people were still making this argument.

These things don't exist without human interventio.n

There's indeed a huge difference between asking the AI to just generate something with a short and generic prompt, and directing it far more specifically. To use the dragon tattoo analogy, it's the difference between asking for "a dragon tattoo" and precisely specifying exactly what type of dragon, what pose, colours, any other adornments, etc.
