I think the point here on Joy Division has less to do with the actual statistics of how many people list Joy Division as a band they like, and more to do with how much relevance music has in the younger half of generation Y as a status icon of "who I listen to". Sort of how like, when I was growing up not many 12 year olds could hit a jump shot from the three point line as often as one of the neighborhood boys (who we'll call Anthony) could, but your status as popular or not in the neighborhood completely depended on your ability to hit a jumper.

It's not a thing of statistics as much as it is a remark about the culture of being "relevant".

Just wanted to share an opinion on that tangent.
