Talk is cheap in the music field.
Labels abound and everyone's got a right to an opinion, whether that opinion may be qualified or not. To me, it's the difference between a good and bad tune or performance. Nothing else really matters anywhere near as much. Music needn't be harmonically complex or technically dazzling to emotionally move a listener, though many get sidetracked by the more cerebral or physical aspects of our art. Blues music, probably to a more apparent degree than other styles, hinges on delivering a message or story, with a lot of feeling as well.
