Electronica
I was actually thinking about proposing an article at the end of 2007 called "The Year of Electronica," in which I make the argument that some of the best albums of the year are direct descendants of that horrible word no one has used in a decade. LCD Soundsystem, Justice, Klaxons, Simian Mobile Disco, Chromeo, Datarock, and, if you stretch it a bit, Kanye, M.I.A., Battles, Mark Ronson. But then Slate published it. Dammit. (I like my examples better, and I would have slipped in that Kanye quote about creating a new kind of electronic hip-hop.) Noted: Idolator quibbles with some historical points.
