I had a hard time getting Internet radio stations to work until I did a back up and looked at the PLS (playlist) file. I was then able to see the format of the url.
Open the Audio Player and click on the menu opener (the 'v' next to the title bar on the top left of the Audio Player). Click 'Playlist' and then 'Add Stream'. Enter the web address of the radio stream. For example, if you go to http://accuradio.com/mobile/ and click on one of the pictures of the available radio streams for mobile devices you will download a PLS file. Open that with a text editor to see the url.
NOTE: After adding a stream go back to the playlist menu and click Save or your addition will be lost.
existed already a list ?

An overview (internationally) in one thread would be helpful for all - perhaps even in a Wiki
