A singer is someone who can "put over" a song in a way that will make you listen. Good, great, fabulous, voices of high musical quality, range, purity and integrity are everywhere but the majority of these voices are cold, featureless and unmemorable. It is easier to get a grip of something with a rough surface that one with a smooth surface so the imperfections and flaws, the twists and turns, the limitations of the singer's breathing and hearing is what your brain gets to grip on. What you like and don't like is something else. As for modern day singers, they all rely far too much on microphones and amplyfiers. They might have great stage pressance and good microphone technique but most of them cannie sing.
