But whether you realize it or not, that is exactly what you have been arguing all along.

You're complaining about the artist's desire to recoup money that they invested into creating the recordings you downloaded and are enjoying, making it like they're assholes for expecting to be paid for rendering a service that you clearly find valuable, talking about "when are they gonna grow up?"...

...and you DON'T think you're expressing that you feel entitled to download music?

If you don't see that, then it's likely you don't know the meaning of the word "entitlement."
