I agree, to a point. I think Steve Perry had a truly great voice....he had a voice like a bell.
I didn’t mean all of them. Some of that 200 really do have great voices. There are also categories for great voices.
Some of those people may have a unique voice that works on certain songs, but if they get out of the range where their voice works, they can stink.
For instance, Kelly Clarkson has a great voice and it is a versatile voice. She can sing songs I do not like, but she still has a great voice.
