What are you listening to right now?

I like to growl, not mumble. Also, a growl is not the same as a roar, and it's difficult to do it "under your breath," and even then, it wouldn't really be a growl.

As for a scream, I can't do it, or rather, recently, as they say, something decent has appeared, but in my opinion, it's garbage, not a scream. And the growl needs to be improved. I've been working on it every day lately.
