No, really, he sounds pretty good: Planet Money Episode 449: The Hidden Digital Wealth in Your Pocket. (If you have no patience at all and can’t wait to hear Rick’s mellifluous voice, his on-air quote starts around the 4:40 mark. But you really should listen the whole thing.)
You can read Rick’s blog posts on ReDigi’s attempt to create a market for “used” digital downloads that got Planet Money’s attention, or just cut to the chase with his latest on the district court’s ruling that ReDigi violates copyright in doing so (if you can stand all the mixed cake metaphors).
