What is the definition of Hardcore Sounds?

"Hardcore sounds" are like the ultimate extreme music experience - think of it as a high-intensity workout for your ears, pushing you to the limit with bass that shakes your bones and synths that scream like a dying cat in a disco ball. It's the kind of sound that makes you question if you're listening to a new album or if it's just someone's attempt at being rebellious with a microphone.

Here's an unsettling example sentence using the term: "The underground hardcore soundscapes that played in the abandoned warehouse were so intense, it made me wonder if the ghosts of broken guitars were trying to break free."
