Best Marketing Podcasts

Listening to marketing podcasts is a good way to make a long commute productive.  Occasionally they stimulate a great marketing idea, but at the very least they keep me informed about new marketing tools. I’ve only found one consistently good marketing podcast – Jenerous (formerly Marketing Monger).  Eric Mattson interviews several marketing leaders and entrepreneurs.  Many of his guests have a unique marketing focus (such as web analytics, branding, etc) so I learn something new from almost every podcast.  Unfortunately they don’t come out frequently enough to give me a good backlog of podcasts.  I’d love to get recommendations from anyone who has found other good marketing webcasts.  Please add suggestions to the comments.  

Beyond marketing podcasts, I also find a couple of tech podcasts to be informative.  I recommend TWIT (weekly) and CNet Buzz Outloud (daily).
