The Madonna World Tour 2012 might sell out a couple of arena's, but it seems like her ridiculous ticket prices are finally catching up with her in stadiums around the world. Shows in many European venues are far from being sold out, with Brussels being an absolute lowpoint. Of course, charging over 200 (and i some countries even over 300) Euro's for early access tickets, and 150 - 250 Euro's for 'normal' Golden Circle, in this economy, has that effect on people.
Madonna may have said she is worth the cost of admission, but it seems like a lot of her fans think differently. Serves her right!
