"Napster affected rock CD sales disproportionately when it first came out in the late ’90s, because rock was what a lot of college students were listening to, and they were early MP3 adopters (and early pirates.) They figured out quickly how to download MP3s for free, so rock sales were the first to decline. It would take a while before piracy/the Internet/MP3s/downloads would cut into other genres, because it took old people a long time to figure out the Internet."
