My standard mix

The Joe Rogan Experience - Joe Rogan interviews people he finds interesting. Fighters, scientists, youtube/media personalities, complete nutjobs and every mix and variation thereof.

Hardcore History [Dan Carlin] - Lengthy, thorough outlines of major events/periods of world history. Maybe 5-6 episodes produced a year, but they are doozies.

Common Sense [Dan Carlin] - Carlin's 'Martian Perspective' on US Politics/Current events

Stuff You Should Know - Produced by Discovery Networks HowStuffWorks.com, Josh and Chuck talk about a potpourri of topics. A personal favorite since high school.

Waking Up - Sam Harris talks at length with guests about religion, atheism, artificial intelligence, neuroscience and myriad related topics.

Verbal Violence - Recorded live at the Comedy Store in L.A. , Verbal Violence gives you a front row seat to the Roast Battle where up and coming comedians take turns humiliating and debasing each other on stage.

Latest additions are

My Brother, My Brother and Me - The McElroy brothers, and sometimes their dad and significant others, take questions from their listeners and give (bad) advice.

The Adventure Zone - The McElroy Brothers and their dad play DnD, hilariously.
