Most people see Wu-Tang as a hardcore/gangsta rap outfit. but the wu is/has been conscious of social and political issues from the very beginning.
Pay attention to Tearz. Very few rap groups encourage safe sex. In Tearz Ghost tells a story of a friend who had to learn the hard way how important it is to protect one's self.
America is Dying Slowly is another wu track in which they cover safe sex and aids
numerous other tracks like A better Tomorrow are socially conscious.
the best known wu track is in my opinion often misunderstood. and that track is CREAM. the track is not really about the pursuit of money. although the chorus and the especially the video (at the end) suggest that it is. it's really about progress in my oponion. in many ways to progress and get out of the ghetto who may need to be financilly in a better position. that's the message, i think, they're tryin to convey
