13,000 is a lot of people for either the US or Europe. The show was successful for Shakira.
Sorry, let me clarify my earlier post. 96% is great; I was referring to the venue seeming 75-85% full to fans who were there. I was trying to answer the "Where did the 11-21% of other sold tickets go?" Either that or forum members can't perceive crowds well/aren't good at percentages.
