Hardcore Punk (Feedback)
Hardcore Punk was the most hardcore punk song you could have, because the only lyrics were, "I am such a punk!"
Currently, you have to take the old hardcore punk clichés, and play around with them a little bit, to come up with some new hardcore punk.
Such as, having an offensive band called "the Banned".
Thankfully, we live in a world where most people have smart-phones, so we communicate with each-other on a larger scale for the most part.
