I listen to Atlanta Monster and Crime Junkie. The host of Atlanta Monster is amazing. The podcast centers around the Atlanta child murders in the 70s and 80s. It's pretty chilling at times. Crime Junkie is also good, although the host can go on at times. Still, there's always a compelling story to hear during the show.
I used to spend a lot of time on the road, and Red Eye Radio kept me company for many, many miles. They discuss current issues, mainly political, but they get into other news sometimes.
