Here are some things that have been useful to me, and some other things that may be useful to you. :)
Dirty Old Ladies - an indie comics podcast that doles out some great advice.
NoSleep - creepypastas (scary stories) read aloud!
The Black Tapes - a truly horrifying fiction podcast. One of the first pieces of horror media to start me writing horror comics.
Spirits - a mythology and lore podcast. Check out their urban legend series!
