I'm using FM Radio with Xlobby...using the WinAmp TV plug-in.
The plug-in allows you to scan for stations and then creates files for each station. I created a XL database for these files as "tracks" so I could display them as a category in XL and make them play automatically through WinAmp
Works great and since the stations are in a database, I added some internet radio stations too.
If you have any questions, don'T hesitate
