RadioTuner – Listen to Any Radio Station via Dashboard
There are quite a few ways to listen to the radio on your Mac, through iTunes, Safari, various Dashboard widgets, but RadioTuner is probably the best way yet. RadioTuner is a Dashboard widget that allows you to customize the list of radio stations, allowing you to hear what you want to hear rather than whatever is in a predefined list (like iTunes and many other widgets provide). For RadioTuner to work properly, you’ll need Flip4Mac and RealPlayer installed.
The interface is small and easy, simply paste the radio feed URL into the widget and save. The developer also has a growing list of searchable station feeds available, searchable here.
