Assuming you can identify it's someone else's IP. Clearly these are hugely contrived examples, but what about text or code that you might not be as familiar with?

Given enough time (... a surprisingly short amount) and enough people creating art (say, about as many as we have had for the last couple hundred years) and indefinitely-long-lived recording, plus very-long copyright terms, the inevitable result is that it's functionally impossible to create anything within the space of "things people like" that's not violating copyright, for any but the strictest definitions of what constitutes copying.

The short story treats of music, but it's easy to see how visual arts and fiction-writing and the rest get at least extremely crowded in short order under those circumstances.

It doesn't matter. Sue whoever uses it commercially.

If you insist on making it about the model, you will wreck something wonderful.
