Smithsonian Global Sound

Amazing site. I can't imagine how long it took them to pull this together. These are folk sounds from all over the world. You can click on a region, choose a culture, or instrument you want to hear - and up come hundreds of sound bytes. You can purchase the entire "songs" if you want to. Just browsing through the collection is illuminating. Try it out: http://www.smithsonianglobalsound.org/geocache.asp
