I have never suggested that at all. I do keep saying I don't know what it is that accounts for my tastes. Up to now ornamentation, major/minor keys and strict tempo have been suggested. You yourself have disproved that the ornamentation and tempo are no different. I like both major and minor keyed tunes. So I am back to square 1. Maybe personal tastes are just random, but I doubt it. It does link back to the question in the OP and maybe the answer lies in the linked articles but I have not yet spotted it.
