You listen to the same podcast 50 times because you like the company in the car.
In March I listened to the Dream Review & Christening Podcasts over and over and over again. We were getting ready to sail on the Magic and I just kept listening to them until we left for our cruise. And, when I have listened to all of the podcasts in a week, I go back and listen again and again until the new one comes out. I haven't listened to the radio in months!
