I just finished listening to 'how to get rich' by dennis felix, which is a good light, humorous book. Take everything with a pinch of salt, but mixergy.com has some good stuff. Ecorner.stanford podcasts are all pretty damn good, harvardideacast and knowledge@wharton are interesting but not to the same level. Can also recommend venturehacks and venturevoice podcasts for customerdev/marketing entrepreneurial stories.

I listen primarily when running or at gym, killing two birds...
