I've been enjoying one called "Just good music" it's an electronic music podcast. you can find it on itunes. and i say electronic because it varies each week, but it's mostly house and blippy, minimal techno (which i like a lot).
Smithsonian Institute's Tapestry of the Times is a weekly podcast of recordings from the Smithsonian Folkways label, a huge catalogue of "all organized human sound from around the planet." It's very strong on American folk and blues but also ethnic musics from around the world. Each episode is a great listen and a bit of an education. KCRW's level-headed political debate show Left Right and Center is available via podcast. Good stuff. So is NPR's Science Friday show. If you enjoy classical music, WGBH's Classical Performance Podcast offers weekly performance of entire pieces, usually chamber or solo works. Really nice. If you like Latin music, especially "Latin Alternative" and not the sucky pop stuff on most Latin radio stations, Ritmo Latino is consistently superb. That show has turned me on to a lot of acts that I wouldn't have come across on my own. A real melange of styles. Sometimes the host throws vintage music into the mix. (The host speaks in English FWIW.) Although the podcast is officially defunct now, the entire back catalogue of The Dorktones Podcast is still available via iTunes subscription. I can't recommend this one strongly enough. Hard to describe, but it's basically rock, r&b, psychedelic, new wave, punk, etc. from about 1962 through 1982. Just amazing. Best podcast ever IMHO. I thoroughly enjoy Mark Kermode's weekly BBC Five Live movie reviews podcast. Kermode is usually spot-on in his comments and is a riot to listen to with sparring host Simon Mayo. Super-entertaining.

I'm really into a lot of the CBC podcasts... I love "White Coat, Black Art;" if you're in the medical field, or just interested in medicine, check it out.
I used to listen to this all the time. Then I noticed he kept playing the same records over and over.
