The following image is from the wikipedia panel of amarok when I've just been listening to some Hans Werner Henze - for whom there is a perfectly good wikipedia page (follow that link!)
I'm not sure whose fault this is, whether wikipedia is seeing a request from amarok and trying to find a band and failing or if the responsibility is at amarok's end. It illustrates the sort of hole you get in when you assume that everyone fits a particular template - listening to bands who play songs. We are all individuals(!) who may think differently to the writer of a particular piece of software - and when the assumptions of the writers of two pieces of software don't mesh then you get screen shots like this.
