The reluctance to turn off the radio when a good song comes on. Most commonly upon arrival at a destination in your motor vehicle when you would rather sit in your vehicle and listen to the song, as opposed to getting out of your vehicle.
Paul (boss): You're 3 minutes late Rico. You're fired!!
Rico (worker): Sorry Paul, I had radio remorse.
Paul: Ohhhh. That happens to me all the time. No worries, you still have your job.
Rico: Whew. I'm glad another good song didn't come on!
