Joe Rogan will occasionally have guests that attract people who wouldn't otherwise be interested in common JRE topics. In my case, it was podcasts with Billy Corgan and Shirley Manson (of Smashing Pumpkins and Garbage, respectively).
I enjoyed those episodes a lot, plus a few he has with comedians I find funny. But it wasn't enough to make me subscribe. I doubt there is any podcast that I consider indispensable enough to subscribe.
