Being entertaining, and being highly political, are not mutually exclusive. In the folk music realm, you should experience Utah Phillips, or Tom Paxton, or Si Kahn, or Pete Seeger, or Arlo Guthrie, or Joan Baez, or many others who are skilled at weaving heavy duty politics into entertainment.

Of course, listening to political music devoid of entertainment value can be very excruciating. I recently went to hear David Rovics. He sang nothing but very shallow, slogan-laden songs. It was painful to listen to.
