Stream Instant Tours Via Pandora

I love to vacation.  One of the most amazing trips I've taken was to Italy.  I was surrounded by statues and building and fountains that were hundreds and thousands of years old.  It was totally awesome.  I was also surprised at how many of the places we visited offered tape recorded tours.  You would pay an extra five euro and you would stroll around listening to a professor of some sort telling you all about the museum's pieces.  It would be cool if you could create a free database of tours.  Something like a Livabox.org or Pandora for tours.  You could collect a large selection and not have to pay the extra five euros at each stop for a top rate experience.
