Big THANK YOU! I love old time radio horror. Every night, I listen to internet radio- usually Horror Theater, Old Valve, or Mystery Play Theater stations. My fave shows are the CBS Radio Mystery Theater and Inner Sanctum Mysteries.
The Horror and Strange Tales update every weekend and are regulars on my ipod, the Scifi is more hit or miss. The short story is sometimes horror related, and the Thrillers tend to be more crime related but can certainly set the tone as well.
