#1 S-Town

S-Town is a new podcast from Serial and This American Life, hosted by Brian Reed, about a man named John who despises his Alabama town and decides to do something about it. He asks Brian to investigate the son of a wealthy family who's allegedly been bragging that he got away with murder. But when someone else ends up dead, the search for the truth leads to a nasty feud, a hunt for hidden treasure, and an unearthing of the mysteries of one man's life.

#2 Serial

Serial is a podcast from the creators of This American Life, hosted by Sarah Koenig. Serial unfolds one story - a true story - over the course of a whole season. The show follows the plot and characters wherever they lead, through many surprising twists and turns. Sarah won't know what happens at the end of the story until she gets there, not long before you get there with her. Each week she'll bring you the latest chapter, so it's important to listen in, starting with Episode 1.

#3 This American Life

#5 Dan Carlin's Hardcore History

In "Hardcore History" journalist and broadcaster Dan Carlin takes his "Martian", unorthodox way of thinking and applies it to the past. Was Alexander the Great as bad a person as Adolf Hitler? What would Apaches with modern weapons be like? Will our modern civilization ever fall like civilizations from past eras? This isn't academic history (and Carlin isn't a historian) but the podcast's unique blend of high drama, masterful narration and Twilight Zone-style twists has entertained millions of listeners.

Child abductions are rare crimes. And they're typically solved. For 27 years, the investigation into the abduction of Jacob Wetterling in rural Minnesota yielded no answers. In the most comprehensive reporting on this case, APM Reports and reporter Madeleine Baran reveal how law enforcement mishandled one of the most notorious child abductions in the country and how those failures fueled national anxiety about stranger danger, led to the nation's sex-offender registries and raise questions about crime-solving effectiveness and accountability.

#20 Pod Save America
