Its odd that with all the items on this list which have such broad definitions like "classical" "punk" "new age" and "classic rock" we also have this, which is easily and narrowly defined.
An extremely early form of sacred music, dating back about 1400 years, it has a fine sonorous resonance.
I like it, although in small doses, and I'd be curious to hear a Gregorian/hip hop fusion band.
