Take a look at a native site called Oyate at http://www.oyate.org/. They started out with books but have film and music recordings listed in their catalog also.

I took at look at Kids Pow Wow Songs. Those are not your usual kiddie Barney or Mighty Mouse songs, by any means. The Black Lodge Singers have released quite a few CDs over the years. Amazon has some samples, you would do well to listen to them. GUEST,Foe would have done readers a favor by expanding on his/her recommendation. These songs are fine examples of Indian appropriation of mainstream material.
