About the Music field: yeah def pointless to have a space for Episode in the Ep's page. I had just copied the row from Music, but your edit makes sense. They used to have a field in episode pages about where to purchase the track, but I left that part out because looking around it seemed several users didn't want that. It's def a loaded question now, don't want to be seen as promoting Amazon vs Apple vs Google etc.
I'm thinking we should probably remove the field in the table along with in the rows, wondering if it should be replaced with anything in particular (could see a link to the lyrics or youtube or something, but again that's getting into promotion issues). If you have thoughts on that, great. If not, I'll just remove the field from the table; if someone else wants to add another column.... good for them (in a not passive-aggressive way).
