I don't see all the fuss about Chuck Billy. He's decent enough to not be noticably bad, which I guess makes him one of the better thrash vocalists, although that's not saying much. He's not even a great frontman, he just kind of stands there (I'm basing this off one live video BTW, so I apologize if this is wrong) But as far as I care, the only two thrash singers worth mentioning are Blitz and Belladonna. The rest are pretty interchangeable.
