I think it is a great idea to create a list of chanting links that allow people go, see and compare. But I find that a number of things are missing here, such as Russian Orthodox Chanting and Northern People's chanting. Russian orthodox can be found here, for example: www.red-music.us/artistpages/fatherherman/index.php

and Chuckchi throat singing is here: www.mp3.com.au/Track.asp?id=21814

Throat singing is practiced throughout parts of Asia, Northern Europe, Africa and India as well.

Yes, but not only there. Chuckchies also practice throat singing, or to be more precise, throat rattling, when the sound starts even lower then in case of throat singing. Some other Northern peoples, such as Yakuties and Evens have a similar singing tradition.
