Not sure if everyone has seen this cool widget yet. It is called Radio Tuner.
RADIO TUNER WIDGET

It is very easy to add stations. Just go to the add station in the dropdown menu, add the name of the station on the first line and then the link on the second line and then click add.

Don’t forget to click on the arrow to play your radio station. You can also change the color of your radio tuner...mine is purple.

Below are a list of Italian radio stations I have added - all played by real player and so you don't need to download the Flip4Mac plugin to for these stations.

*some of the links will play the stations also directly from real player without needing the Radio Tuner widget.
