Listening to radio in the computer

No...internet radio stations shouldn't charge you to listen to them. I regularly tune in to a rock radio station online called 525.com and it's absolutely brilliant. To my knowledge they don't charge and I have been using this site for a good couple of years now so would have thought they would have charged something by now if there was a fee to use it. To my knowledge it doesn't download anything to your computer either your just tuning in to the live streaming.
