no one rejects tunes,as folk tunes because they have been composed,or becuse they have been processed.
however Neilidh Boyle complained that nobody played the moving cloud as he wrote it,which is fair enough,a composer of a modern tune has a right to say that he wants the tune played in a certain way.
likewise a composer of a modern song has a right to state that he wishes a song to be sung with certain words,particularly if the processed version changes the meaning of the song.
if their is an alteration to the mood of a tune,by some processor [e g changing notes to alter a minor feel to a major feel]the composer has a right to object,and to say the tune should be played like this or like that.
