I listen to "This American Life," "WNYC's Raido Lab," "The Onion Raido News," "On The Media," are all staples regulars but I also like "The Sound of Young America," "The Little Gray Book Series," and there are a handful from Nat Geo that I'll watch/listen to now and then...
As for Shahram having his own podcast – that might be okay but odds are he's got a high-pitched little grrls voice.
