What are people listening to when walking around with earphones plugged into their cell phone

You don’t know that radio stations have apps for iphones and androids? I have about 6 apps for radio stations and NPR. I don’t need to have a chip enabled. I have never even heard of that. On apps you can see playlists, comments, the website etc.

Maybe if I just get some chip I can avoid all that convenience? I have no doubt that tuning station to station on that chip will create some new “problem” I didn’t want.

What we might need is one app that coordinates all the radio apps under one command.
