I listen to a bunch. Favourites are Conversations with Tyler - American economist who just has the smartest guests. and the British History Podcast, to fill the gaps in my historical knowledge of the UK (i.e. almost everything). Killa Kela has done some great graf interviews and F24 is good as well for that sort of thing.
"The Caliphate" (by Rukmini Callimachi)about the fall of Mosul, ISIS and the recruitment of an ISIS member is a stunning piece of journalism btw.
The first (only so far) season of Bellingcat about the shooting down of MH17 is also amazing. Both give you the thrill of that kind real crime investigation as they stack up the evidence. Bellingcat is very good for a sense of what open source investigation is and what it can do.
And this reminded me of.....
Popular Front - geeky details on modern combat and conflict, normally with very informed field researchers. He's just been in Hong Kong though I've not listened to that one yet.
I also listen to Rune Soup for occult stuff and it's usually excellent though when he talks about politics I tend to want to kick him in the teeth. Occult podcast dude believes that everything is a conspiracy, who'd a thunk it?
I've found that as well, they've taken over from music. I think it's got to do with the ease of use of the platforms, and the stream of new content pumped out. Music I have to be more decisive about - think about what I'm going to listen to, get access etc.
