Oh, come on, Aine -- there are lots of traditional songs which haven't got a political message. Though I'm sure you can find lots of exceptions, in general

Broken Token songs aren't political (eg A Fair Maid Walking)
Hunting songs aren't political (eg Dido Bendigo)
Drinking songs aren't political (eg Oh Good Ale)
Boy meets girl songs aren't political (eg Banks of the Sweet Primroses)

You may not share his opinions, but I can't see how you can disagree with what he says.
