Piracy?

[BrianSoddingBoru4]

Say I hear your song being played, I never signed anything saying that I would not copy or alter that work for my own benefit.

I've never signed anything saying that I would not steal your car, burn down your house, or murder you in your sleep. Does that give me the right to do it? Don't be daft. A copyright isn't a contract between two parties, it is the right accorded a creator of intellectual property to protect his or her work.

It's your fault for letting me hear it without having signed anything.

Suppose I write and publish a novel. Does reading it give you the right to plagiarize it?

The rest of your post simply boils down to an attempt to justify theft.
