Imagine running out of podcasts. My problem is I have way too many. Revolutionary Left Radio is incredible whatever the subject. Citations Needed has great media criticism. The intervention is pretty good, covering Palestine history, Capital, and other things. Trashfuture is about British politics, but I find it hilarious as a USian. Qanon anonymous is a great podcast that covers far right conspiracy theorists mostly in the US. If you like detailed history (I’m not the biggest fan), there’s Programmed to Chill, Revolutions, Blowback, and People’s History of Ideas. Marx Madness is good for enhanced audiobooks. Chunka Luta finally has a podcast, and it’s first episodes have been good.
A list in no particular order. Note that I don't 100% endorse all of these and claim they are explicitly communist, but they are at least in the wheelhouse and worth checking out:
Geopolitical Economy Report (G/E)
Guerilla History
Rev Left
Red Menace
Labor Jawn
Blowback (all seasons, my favorite was S3, Korea)
The People's Forum
Mother Country Radicals
Rigged
Drilled
Verso
Downstream
Dispatches
Michael Parenti Collection
Citations Needed
I forget which of our comrades here uploaded it, but the Michael Parenti Collection is a great addition to all the other ones mentioned here.
Special emphasis also on the Guerilla History and associated podcasts though!
Downstream by Novara Media has interesting discussions as well. They don't always invite leftists on, but the hosts are socialists and provide good discussions. Occasionally they have some bad takes, but overall good.
Dispatches with Rania Khalek inviteson many interesting guests. I particularly enjoyed the episode with Cuba's foreign minister.
I prefer to watch G/E instead of just listening as Ben Norton puts articles and other documents up on the screen sometimes.
If you want to slowly lose your sanity, I recommend Ghost Stories for the End of the World. It's a podcast about the intersection of intelligence (agencies), mafia, and the supernatural.
Lots about the CIA, Gladio, and other horrible shit the western governments got up to.
i've mostly stopped listening to "serious" podcasts (aside from blowback when that comes out, and the occasional episode of citations needed) and now listen mostly to communists talking about the politics of childrens cartoons
a more civilized age: covers star wars in vaguely chronological order, talking about the political and philosophical implications of the worldbuilding therein. most of the podcast is covering the clone wars and rebels kids shows, but they do the movies and live action shows as well
the great gundam project: 2 people watch all of gundam in release order and become communists along the way to understand the worldbuilding better. great coverage of a fascinating franchise that covers so much ground
the shrieking shack: people who grew up with harry potter revisit it as adults to talk about just how rancid that series is and how dogshit the writing is in the later books. has the bonus of coming out as jkr started to go mask off so if you're curious about her journey there they cover it in a lot of detail
homestuck made this world: leftist academics talk about homestuck and why it's a fascinating microcosm of the broader internet and how culture has developed
Marx Madness for theory, Chunka Luta for modern indigenous liberation, and 5-4 pod for shitting on the Supreme Court (though, because it's within the framework of the current settler government, it can sound a bit on the liberal side, especially in the earlier seasons. It's still enjoyable though because they do point out the hypocracy within the system even if you're allegedly playing by the rules)
Edit 1: Also, Some More News/Even More News are pretty good if you like a little bit of comedy with your existential crisis.
Edit 2: The Minyan if you like to learn the intersectionality of Judaism and communism. Episode 15 is a 5 hour long analysis of the Exodus story and why the biblical/talmudic versions are completely fucking wrong.
Paved with good intentions? the Iraq invasion and us empire
Unlocked - the never ending decline of the UK
Never Trust Imperialism
Forget Theory!
These are some just scrolling through the list of eps that jumped back out at me. I can give you more but it will take me some time to scroll through and recall. Happy listening. If it's not your cup of tea, no harm no foul... Just thought I recommend something trying from a non western perspective that brings around people that few hear from.
