I don't know what else you could do that is more vulnerable - maybe dancing - than singing.
Adam Schlesinger
As a writer, I find it very satisfying when a lyric suddenly ties together more neatly than you expected it to. But for the listener, hearing a good lyric is not generally as exciting as hearing a great beat or a great riff or a great melody or even a distinctive singing voice for the first time.
Adele
I've been singing properly every day since I was about fifteen or sixteen, and I have never had any problems with my voice, ever. I've had a sore throat here and there, had a cold and sung through it, but that day it just went while I was onstage in Paris during a radio show. It was literally like someone had pulled a curtain over it.
