And for the note Jennifer Holiday and Lara Fabian are both well known and respected singers around the world, not like a simple Broadway and Belgian singer. And if you don't know them, sorry but it's your miss. I mean I am a metal/rock listener since my teenage time and I learned Jennifer Holiday by chance and she is just a vocal power house. I listen some of her music time to time.
Look...I can't speak to "the world." Based on the brief search I did, they've both had long careers and success. Good for them. But there are tens of thousands of professional singers, and I can't know them all, so no, it's not my "miss" for not knowing them. I know and like Philip Quast, Colm Wilkinson and Lea Salonga, but I'm not going to pretend that it's sad if they don't make the top 25 here (I didn't put them on my list) or that it's others' "miss" if they don't know them.
Michael Kiske is easily BY FAR my favorite singer. He's quite well known for his high voice, but his range is ridiculous. His low end is strong, and he's as powerful as there is.
The "I am the one; doom's in my hand" part from "Halloween" demonstrates that quite nicely. His range on that song alone was crazy good. Tucking your t-shirt into jeans, OTH, not so much.
Cornell isn't a guy I knew by name until he off'd himself, and I vaguely knew that one Soundgarden song that got some radio play and another one that was on Guitar Hero. Decent enough voice, but I was not a fan.
That one song? Soundgarden had 14 songs that charted on Billboard's mainstream rock charts, 6 of them at number 1. I know it varies by region, but in my area were all over rock radio throughout the 90s.
I had all but stopped listening to music on the radio by the mid-90s. As far as "that one ... song," I believe I was referring to Black Hole Sun. Looking at their discography...Spoonman is the song from Guitar Hero, and Outshined rings a vague bell. None of the other 14 songs that made the U.S. mainstream rock charts ring any bells at all
