Also, "World" usually means "not in English," rather than simply "not American, etc". Music from Western European countries like France or Spain are usually found in "World" sections, so too would be a French-language rapper from Montreal, probably. Although some stores have a "Latin Pop" section (usually next to the "World" section, by the way) usually California or Texas bands that sing, in Spanish, in a Latin American/Mexican style, are more likely found in "World" sections than elsewhere.

But the reason why "World" is a useful term is that it's vague enough to encompass anything it wants to, and can be easily divided into subsections. Most cd stores, if they have a big enough selection, will divide the world section into continents or regions, and then, if their collection is extensive enough, to styles or countries within those regions.

But, really, who cares what anybody calls it? Youssou N'Dour might possibly be the most famous musician in the world, but he's well below the radar in the states, and giving his albums a different designation isn't going to change anything about that. And that's all the article seems to be advocating: a change in terminology, which is only a change in thinking in that the acronym supposedly doesn't have whatever derogatory associations "world" does.
