Who Charted? is wonderful. I was only marginally familiar with Howard Kremer, but he's a delightful weirdo. He and Kulap have really great chemistry.
Speaking of Kulap, her recent appearance on The Mental Illness Happy Hour was especially harrowing. I listen to that show occasionally, not because I haven't enjoyed what I've heard, but because the subject matter is often pretty grim and it gets depressing if try to listen in large doses.
