I guess all music could fall under this category, insofar that all music is from this world. World music is something that was coined back in the 1960s by Robert Brown, an ethno-musicologist, a term the music industry has used to classify any kind of music that comes from non-Western parts of the world. This is the place you'll find the celtic, the reggae, the klezmer, the afrobeat, the Indian ragas and latin-influenced grooves, music influenced by culture and sounds indigenous to other parts of the world. This is local music gone global.
