All the acts featured in the list were touring last year, and interestingly, although Madonna has the highest figure by some way, her album Hard Candy only managed to scrape into the top 50 best selling albums of last year.
By the end of her Sweet and sticky tour in the Autumn, which is the only one ever to be extended, Madge will have been playing a significant number of stadiums, meaning a ker-ching factor of serveral million $ per night in earnings with a large portion coming from merchandising.
