Guys, what's wrong with you? We had lots of complaints from Argentinians about this tour (you can imagine there was no complaints from Brazilians). We changed title of the tour and title of all windows to "Iguassu falls, Argentina-Brazil, virtual tour", we changed map to show what view points are located on the Argentinian side. So I don't think the word "ignorant" is about us. You probably have to think that music is international treasure and has no borders. We use English music on our Russian tours and nobody cries. We are not going to use Tango on this tour because it does not fit the situation. It's a "city" music. Porbably we'll try to find something you may like.
