I said a while ago I was going to do it, but I never got around to it. But now I have. Here are a couple of text files that simply contain a list of all the episodes in either high quality or low quality. Both of them have the same version of the first 5 episodes because they never had two versions, only one. Also the low quality one still contains a couple of supplemental episodes that weren’t made into low quality. So using either of these files will get you every single episode, even though not every episode had a low quality file. Aren’t I good

Enjoy! And thanks for listening

Hi-Quality MP3 list
Low-Quality MP3 list

How can I use these?
I recommend you try using wget for Linux. There’s also plenty of compiled versions for Windows to choose from. Wget can parse these files just simply using wget -i episodelist[high|low].txt (obviously use high or low depending on which one you have!) in the directory you have the text file. Wget will download all the episodes into that folder. YMMV using other programs, but anything that can import a download queue should be fine!
