On my spotify, I have the following listed under 'podcasts': Intercepted with Jeremy Scahill, Chapo Trap House, Jacobin Magazine's The Dig, and Working Class History. I'm really only a fan of the last one.
I think spotify has a very limited amount of leftist podcasts. Maybe I should use itunes or soundcloud?
Could try various offerings from Channel Zero or the A-Radio Network? At the Cafe and Living the Dream both have strong libcom links. Could also have a look through The Final Straw's links section and IGD's podcast tab. I can try and come up with a fuller list of ones I sometimes listen to, but that should give you a fair amount to look through.
