I posted this link on another thread but it is too good to leave there!

I don't want to comment on any of the choices myself but I will start the arguments if you like...

I don't believe that songs change history. Well, not any more. When song was the way to get to people then yes, maybe, but now other media is far more powerful. So while some of the songs could well have changed history in the past I don't think they do any more. They reflect and report but at best just change fashions. Which is something that someone described as that awful it need to be changed every few months anyway:-)

Enjoy
