I think you missed the point.

Clearly they're not willing to pay for it, if they're downloading it. A sample CD has nothing to do with 'advertising' it has to do with making money. Basically using that logic, if some one steals your websites entire theme and uses it as their own, its good advertising for you.

Those who have never been in my situation, or millions of others and think downloading music is ok, will never understand. But it does in fact hurt people, especially those who aren't signed to big labels. That is a undeniable fact. If you want to come up with lame excuses to make yourself feel better, so be it.
