Way to go Kev. The man knows his s**t. I dig Madonna, but she gets a lot of credit where it isn't due. If anyone is a pioneer it is definitely Bjork. Even Madonna copped her "Bedtime Story" song. Bjork's video was much, much better and very provacative. Madonna was an innovator a long time ago, now she just uses the best person in the current "thing" and takes all the credit for breaking new ground as a major artist. That's why most up and coming artists don't want to work with her. I have to hand it to Madonna though, she still knows how to sell herself.
