'Music detective' tech

The music business is still suing individual file-sharers (see this latest example, reported by the Associated Press), but the newest front in its war on copyright theft is social networking – not just in tunes downloaded and shared, but in the background music of videos upload to YouTube, MySpace, and other social and media sites. To help music fans at your house understand how these companies are using technology to detect pirated music, see this article by CBS tech writer (and SafeKids.com publisher) Larry Magid. Halfway down in the article there's a link to Larry's audio interview with Jim Hollingsworth, an executive at the company, Gracenote, that provides MySpace with that copyright-detection tech. He explains how it works.
