iTunes supports Internet “radio” stations; you can choose one of the available stations and listen to its content similarly to how you listen to a radio station over the air. (The stations are actually Web sites that offer streaming MP3, but they are analogous to radio, so using that as a model is a good way to think about them.) iTunes offers a number of genres from which you can choose, such as Pop, Classic Rock, Jazz, and so on. Listening to one of these stations is much like listening to a CD (or any other source for that matter).
