Its genius. Replaying the best bits during off or weekend hours. And the segments contain three or four replayed bits, strung together with the rotten radio promo in between.
Listen long enough, you hear the same bits played, like repeated songs on Pandora. Deep Throat Informant talks Tuna, Jerry calls Felix Jones with Wade, Gay Cowboy song by Corby etc.
Filler for lack of JV talent or ambition you could say. Cat has made it clear elsewhere that rarely is he approached with new show ideas to fill the time Rotten is on. But entertaining filler nonetheless.
