It is a good song and is not attempting to " pass" for anything. You can't seal music into a mythical past, it Will just keep moving forward , creating new traditions and genres. I am not aware of any other style of music that has this constant bickering about definition. I am huge fan of opera, I do,t ever recall sitting around and arguing about is opera. Same goes for po. Why is this such an obsession with some folk enthusiasts .?
