Chet W....I agree with you completely but again....you are only talking about ONE type of rap. That is like a person only listening to IRA rebel tunes and dismissing all Irish folk music because they find it to be too violent. You obviously know that there are other types of Irish folk musics...and we can put those IRA tunes in historical context...just as the Wolftones do when they perform them. Of course with rap we are dealing with the present BUT the rap you are listening to is referred to as "gangster rap." There are many more rap artist who have positive themes...try Lauryn Hill, Will Smith, TLC, Salt and Peppa'...and the list goes on and on. I am not dismissing your argument...only trying to tell you there are other great types of rap out there....and yes, they are often polyrhythmic...LOL :)
