But unfortunately, like almost all media outlets, finding an actual link that points to an actual mp3 file is very time consuming and difficult.
Here's an example ...
Let's say you want to download an episode of 1-A to listen to on an airplane. The front page of the website[1] has "listen" links and also a "subscribe to the "podcast"" link. But I don't want to "listen" and I don't want to subscribe to anything and I don't use itunes (or anything like itunes).
So you click the link to the actual episode of the show[2] but once again ... cute little "listen" link ... cute little "discuss" link ... but no way to download a file.
So now it's getting frustrating ... but as a last ditch effort, you turn off your brain and just type in "download 1-a episode" into google and come up with this link[3] which takes you to a different website (npr.org) which has a list of 1-a episodes (and our friend the "listen" button) but also has a cute little "..." button that expands into choices, one of which is "download".
