Folk music in JI

Dear All,
Would anyone know of any collections of traditional folk or devotional music with the JI tunings supplied.

I have been playing with some of the ragas/modes and their common themes as given in Alain Danielou's book 'The Ragas of North India'. I am really amazed by the beauty of the the way these JI/Pythagorean scales are used.

Still, I would love to get a simpler selection of traditional folk songs / chants / devotional songs / children's songs in JI tuning, anything from Bulgarian folk songs to Ethiopian Chanting, to Celtic dance tunes but with traditional tunings . Would anyone know of a collection or even a few gems?

Thanks
Steve
