What Makes You Stay With a Radio Station?

What actually made you stay with a radio station. Was it the jams, the DJ or probably the news? So for me, it's the DJ. If he plays music that is in tune with my mood, I will be locked in. Some people stay because of the news but I have a friend who has developed the habit of just listening to the radio because that was what he grew up with. So, for people to stay locked to a radio station, it needs to evolve by sticking to fresh content and good sound quality.
