"excuse me for stating the obvious, but it is necessary to work out what is not traditional and put it to one side to come near the answer. what we are trying to ascertain is what is considered traditional on friday oct13 2006, not what might be traditional in 200 years time."

Well, if the word "traditional" is causing such a problem, how about calling them "golden oldies" instead??????   "greatest hits"???

I think we go way overboard when we try to catagorize and put everything in boxes.   Songs should not be left in museums, they should be enjoyed.
