SINSULL,

If I interpret your comments correctly, I think we're both approaching this with fairly similar viewpoints. My link was selected by way of example with a view to contasting potential artistic merit with the message it supports.

The German Propaganda Website, holds some very useful images from which to start this discussion, but of course this would be a discussion of visual arts/text and not music/lyrics which may be what the original request was looking for. (Hence my request for a more formal definition.)

I certainly believe that you can find good/great art wrapped round propaganda, but yes, separating the message from the medium is going to be something of a value judgement on the part of the observer.

For most purposes I think propaganda will be immediate in its effect and current in its content/message. It doesn't have to have any artistic merit to succeed.
