I've heard that sound already enough.
I don't know what it's called. Anywho, quite simple, but when the "trying" to sound like scratching comes in, and then the guitars, oh gosh. They are overwhelming and horrid. And the harmonica. Maybe tune it down, and you can succeed at making a better song. Overall, okay.
Wow... competent, well-thought-out criticism. That's rare in these parts. Thank you, sir.
Barring that, I don't think I'll change anything
