While we might have done some wonderful things for y'all with Led Zeppelin, Pink Floyd, Black Sabbath and Radiohead, we have also sent you some terrible crimes against music. And while none of this really compares to Canada foisting Avril Lavigne and Nickleback on you, it's still not great. I'm here to hold my hands up for the collection of nations I call my home and say sorry. If it is true that for every action, there is an equal and opposite reaction, then for every Radiohead there must be a Lily Allen, and for every Police there must be a Sting's solo career. We're trying, but we don't always get it right. Here are the worst offenders I can think of. Please add your own.
