English Jon has a good point about R&B being a joke. I remember when R&B was early Rolling Stones rythm and blues which many people enjoyed for whatever reason. So why has modern youth 'stolen' the term to describe this new crap? Can the content of a pidgeon hole be totally changed in this way? Is this happening to folk music? No, because most folk clubs are keen to label their door as traditional, whether it be a sing-a-round or a play-a-round.
