A few years ago, American consumers should have boycotted all music they couldn't find on Napster. Far too late for this now, of course, but IP really is getting in the way as a search cost: on the Internet, you can type in a few words from the lyrics, and find them on the Web. That then gives you the title, which you could search for on Napster. Having confirmed that this was the song you heard in the club last night, you could then go out and buy it.
