Besides playing back your favorite audio files, iTunes can also tune in Internet radio stations from around the globe. You can listen to any of a large number of preset stations, seek out lesser-known stations not recognized by iTunes, or even add your favorite stations to your playlists.
Although it’s not a radio tuner in the strictest sense, iTunes Radio can locate virtual radio stations all over the world that send audio over the Internet — a process usually dubbed streaming amongst the in Internet crowd. iTunes can track down hundreds of Internet radio stations in a variety of styles with only a few clicks.
To begin listening to Internet radio with iTunes, click the Radio icon located beneath the Library icon in the Source list. The result is a list of more than 20 types of radio stations, organized by genre.
When you expand a Radio category by clicking its disclosure triangle, iTunes queries a tuning server and locates the name and address of dozens of radio stations for that category. Whether you like Elvis or not-Elvis (those passing fads, like new wave, classical, or alternative), something’s here for everyone. The Radio also offers news, sports, and talk radio.
Although iTunes offers you a large list of popular radio stations on the web, it’s by no means comprehensive. Eventually, you might run across a radio station that you’d like to hear, but it’s not listed in iTunes. Luckily, iTunes permits you to listen to other stations, too. To listen to a radio station that iTunes doesn’t list, you need the station’s web address.
In iTunes, choose Advanced→Open Audio Stream (or press Command+U). In the Open Stream dialog that appears, enter the URL of your desired radio station and then click OK. Within seconds, iTunes tunes in your station.
