Soon, certainly by the end of the weekend and maybe as early as today, I will upload to archive.org, a set (almost complete) of the Superman radio arcs, bundled up.
I'm not sure that makes any sense, so let me explain. I have taken the story arcs and combined them all together, where each arc is an individual mp3. This will make it impossible for your mp3 player to skip around a Superman arc and will in turn force the player to play an entire arc.
I realize this kind of thing won't be something you all will want to download and that's fine. Feel free to send comments and criticisms.
