OK I heard this story on This American Life and thought it was really funny. These two artists hired a polling firm to find out what people wanted most in art. They did this for a number of countries and then made paintings for each country both the most wanted and the most unwanted. You can see the paintings and the poll results by visiting their web site.
This was followed by doing the same thing for music. Then they produced two songs, the most wanted and the most unwanted. You can read about it here. You can actually here the most unwanted song here, and the most wanted song here.
