National Geographic has a great new music feature you’ll want to check out. This is a great way for families and just interested people in general to explore world music. Go to the link below and in the upper right you’ll see an a-z place to select genres. When you click on one, it brings up a description of the musical tradition along with samples for easy listening. My computer didn’t seem to need any kind of plug in. So it should work fine.
