Ulster has as many styles of singing as does any other part of Ireland.  I do take the point about adjudicators, though; to my mind, all competitions do is impose a completely arbitrary norm which is inevitably destructive.  The Mods in Scotland, for example, have a great deal to answer for, and I've met some very poor singers who won competitions in the north-east of England for reasons which remain a mystery to everybody but the judges...  Competition, in the end, is ok in a small sense -just for practice- but a disaster when people start to believe that "winning" is important.
