Podcasts are very good for interviews and conversations, which of course can be cleaned up and transcribed but may suffer for it. There are also audio dramas, audiobooks, documentaries, and so on, that are all tightly scripted and can work very well. Some of them may work just as well as longform text and I guess that's what GP prefers. I enjoy audio documentaries a lot though.
