"traditional singers sing traditional songs, ... if they dont why are they called traditional singers, or is it that they only have to have a majority of traditional songs in their repertoire, where does it all end?"

This is not meant to be a personal attack, 'Good Soldier Scweik', but I sometimes wonder what planet you're on! I found your most recent post, from which the above quote was taken, to be completely obtuse!
For a start, how many singers, normally classed as 'traditional', do you know who, "only has 4 tradtional songs out of 50 in his repertoire"?

Surely, whether a singer is classed as a 'traditional singer', or not, is not JUST about repertoire (?) It's also about things like style, cultural background and approaches to songs. To keep banging on and on about repertoire is just silly and does you no credit.
