Can I shock you?
I have never listened to a podcast. To any podcast of any kind.
I don't really know how to do it! Do you stream them, download them, or what? And where do you find them?
As I'm so inexperienced when it comes to podcasts, I'm not really in a position to say what I want from one. I don't really know how they work. But one idea still springs to mind - pick a band or artist with a massive back catalogue and listen to every single one of their albums, in turn, with as open a mind as possible.
Think of it as a rebuttal to the "critical consensus", the one that says that THESE are this artist's "good albums", and THOSE must never be listened to. But what if you ignored this advice? What if you delved into the furthest reaches of, say, Van Morrison, and discovered countless gems beyond Astral Weeks and Veedon Fleece?
I don't know - it's probably already been done before, and it's probably a boring idea.
