I came across this video on you tube and it’s probably my favorite chant. Not that I listen to that many but of the ones I have heard I really like it. Here in Japan I can hear from time to time a Buddhist monk or monks chanting on a tv show (in particular if it is a funeral scene) or very rarely if they happen to be doing so while Im sightseeing at a temple. The Buddhist chanting is ok but it doesn’t grab me the way Gregorian chant does and in particular Credo in Unum Deum. Listening to it is my spa treatment for the soul since I dont go to real spas.
For the history of the chant and the words see http://en.wikipedia.org/wiki/Credo
