Okay gotta BFF @RecDiffs
Best: I think the people agree 102: Preparing the Way is top tier

First: I really think you should start at the beginning, but if I had to pick not chronological it would be 55: Dog-Shaped Dog

Favorite: Very difficult, I've listened to every episode (including the one from yesterday) at least twice but going with 113: Ambient Pleasure Generator for start of Secret Weird Things TM
