The other cool thing is waiting and watching the general populace. The record industry made a serious miscalculation. I find myself smiling in anticipation of the day people's music begins to expire and they all learn the joys of music licensing. I'm betting on a whole lot of people being very pissed. It won't work even on principle.
Music propagates naturally by sharing and repeated exposure.
Any restriction of this process is unnatural, and can never persist. But the point is, they're still going to try. So, watch the advertisements and news.
