I don't know much about paranormal, although these are the ones which I subscribe to in iTunes.
The Economist (quite interesting for learning about the world economy)
Wake Up To Money (essential for keeping up with the finance news each day, beats getting a broadsheet)
Friday Night Comedy
8 out of 10 Cats (Jimmy Carr + Sean Lock = comedy gold. Shame about the audio quality)
TWiT (usually have great guests with a good insight in to tech, not just from a geeks perspective but a business and political side as well)
MacBeak Weekly (because I am a Apple geek at heart and this is probably the best)
Diggnation (there is something strangely entertaining about 2 guys sitting on a couch with their laptops, drinking beer and discussing the hottest news from Digg.com)
So, a couple finance, a couple comedy and a three technology podcasts. I used to subscribe to more, but never had the time to listen to them all so kept my favourites.
