Peter's right, there is no reason to suggest that because one believes a music to be different, that the conclusion is reached that it is inferior or superior.
To return to SO'P's point
You claim to have some knowledge about storytelling - are you seriously suggesting that there is no basic difference between 'Great Expectations' or Les Miserables, and 'Prince John and The Grey Man of Wisdom' or 'The Gillie Dacker and His Horse' or ' The Pursuit of Diarmuid and Grainne' or any other epic length oral tale we have recorded and believe to have been made and formed by the oral tradition?
