I didn't submit a list and even if I did (which I'm jotting down singers off the top of my head while reading this thread), I know like 4/5ths of my list is not going to be on this thing. One of them is a JPop singer, so I know it's not going to be on this list.
But, I'm glad Chris Cornell made it to the overall list. I Am The Highway is a great song with his vocals and the majority of his final solo album, Higher Truth, has great gems that showcase his voice well.
