Hate to break it to you, TYP, but I am 100% certain that you have used game two on Radio Trivia: Podcast Edition before. It was in the very early days, if not the first episode. I know this because I've always wanted to hear the game discussed further, but I believed that there was no chance of that happening. What a nice surprise!
That being said, I've been meaning to ask if you've ever thought of reusing older games. Perhaps feature one throwback game per episode, choose different songs, and invite a different guest host to discuss it. Maybe 100 episodes in is too early to implement this, but perhaps not?
