I appreciate any singer who has a unique voice. That's one reason why I don't like opera. Every Opera singer sounds the same to me since each actor has to fit into a specific role. I want that rough Kanye West style of singing over polished perfection that I've heard hundreds of times before. Anything gravelly is especially preferred. Rod Stewart is the king of gravelly voices.
When you have that unique of a voice, you have to protect it. Rod Stewart put a two million dollar insurance policy on his voice in case that rasp ever runs out. Being known as a playboy, he's more likely to lose his voice from getting a throat STD than anything else. I wonder if he got that covered under his policy or if he was uncoverable for that.
