Does anyone know how much a music DRM system actually costs to develop? The voice of the internets says that it costs at least a bajillion dollars, is a huge financial burden on the music industry and they're passing the costs on directly to the artists. Realistically I'd guess it costs more like a couple of million at the very most which, spread over every product sold for a period of several years, is actually peanuts.
