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.
