What to Listen to during a run/workout

Skimming through the iTunes podcast library, it occurs to me that there are very few GOOD running blogs. Generally, it's some guy with a microphone breathing heavily as he slogs his way through a 6 miler, ruminating about the weather. I have yet to find anything really compelling to listen to (The E Street Band notwithstanding). Music doesn't seem to hold my attention anymore. Being the technogeek that I am becoming (and probably have been for some time), I have a lot of technology oriented podcasts but very little else. If you have a suggestion, post it in comments!
