If the music industries sell the artists' albums as Audio CDs but most of us listen to them by downloading them from the internet, i reckon they should react in the same way. They should stop/limit selling Audio CDs (which can be easily ripped to mp3 files and can be shared via online) and release WMA/MP3 files with DRM enabled. This will affect majority of us people. I don't know whether this works practically but just my stupid idea.
