At one time there were even laws about faithful renditions of “The Star Spangled Banner” in places like Massachusetts. A band arranger then got in trouble because of a flatted chord. I think that kind of policy is ridiculous, and if you dislike what you hear from an artist the answer is simply do not patronize him or her. You have not proved that such things are “self glorifying” (puhleeze! we are talking about style, not about content). But for a person with your sense of judgmentalism you would be at the most peace simply to watch what you feel to be reliably “normal.” No sense putting yourself in situations where you are tempted to be vexed. Maybe that’s even FR.
I agree with your comment that "if you dislike what you hear from an artist the answer is simply do not patronize him or her". I already told you that I have no problem with your comments, until now. "But for a person with your sense of judgmentalism you would be at the most peace simply to watch what you feel to be reliably normal. No need to make that judgmental comment.
