Music sales are up this year (and profits too) but that isn’t stopping Big Music from suing downloaders. “The Recording Industry Association of America said Tuesday it is suing another 532 people — including 89 on university campuses — in its latest wave of lawsuits against alleged file swappers. Since September, the industry trade group has tried to sue 1,977 people in various parts of the country for allegedly trading music illegally on file-sharing networks. Most of the suits are pending. This time, the RIAA made a point of targeting people who trade on university campuses, who are most likely students.”
