It doesn't seem like it should be possible for some poor soul to wind up incurring 60k of damages just for clicking a button to trade "free" music. But it is.

"Easy for a lower-middle class mom to wind up in hock to the RIAA for five figures? Not the RIAA's problem. Don't trade copyrighted music."
