What sort of "interests" should I list on my LinkedIn profile?

I was thinking of adding some of my unique interests like international music, reading novels, etc, in addition to interests like m media, social networking, world events, etc. But then I took a look at the example interests LinkedIn provides, and seriously LOL'd. Some of the examples include, "organizational development, strategic planning, corporate financial reporting, Six Sigma manufacturing...." Yeaaah. Should I only include interests like this?!
