I'm not actively listening to any now but podcasts I've enjoyed include:
Kermode And Mayo's film review. Admittedly these are around two hours but you can always skip the interview. I've kind of fallen into the habit of just checking the youtube channel for the reviews, but you miss out on the amiable banter which is part of the appeal of the podcast version.
The Adam Buxton podcast. I was a huge fan of the Adam & Joe podcast ('Joe' is Joe Cornish who has achieved some fame as the director of Attack The Block and co-writer of Ant-Man and Tintin, basically breaking up the double act in the process), Adam's solo podcast isn't as great but still makes for amusing interviews when he clicks with the guests. It can be a little awkward when he doesn't.
A lot of the guests are minor figures in british comedy and tv, so it's probaby of limited appeal to non-Brits.
Richard Herring's Leicester Square Theatre Podcast (also known by the catchy acronsym "Rehulstup". Another podcast where a former niche British comedy double act member interviews his comedy peers. I tend to only check out the ones where I'm interested in the guests, but it generally entertains. Stephen Fry memorably admitted to recently having attempted suicide recently on one of them.
Let's Drown Out. A youtube series rather than a podcast, but I only used to stick on the audio so it served the same purpose. It's Yahtzee from those Zero Punctuation game review videos playing boring games with his Australian chum and just chatting about stuff.
This is about the only games related podcast or 'lets play' I can stomach because half the time it's barely interested in the games and as just an excuse to ramble on about about assorted nonsense.
Unfortunately it finished for good recently, but the old ones are still fun. I've yet to find a good replacement 'friends chatting' podcast, if that's actually a category that exists.
