All of which reminds me of hearing Brian McNeill telling a story one time and describing a BBC interviewer, who had "all the usual prerequisites for a BBC interviewer: lots of hair, lots of teeth..."

But there is both "quality" (whatever that is; I think it has to do with what endures) and enjoyment to be found in all genres, though some may be more likely to stand the test of time more than others. Music or any other cultural attribute that has already stood the test of time will naturally seem to have quality, and that which has been shared and enjoyed by many generations is likely to continue to endure.
Is this not more or less why we read real literature to our children, hang actual art work on their walls instead of cartoon cutouts, take them to good restaurants instead of fast food places?
