deletion of radio stations

Hi.
I'd like to know why some radio stations get deleted from yourmuze...
Yourmuze is the only way to listen on my mobile phone, so if the stations are deleted, I can't do it.
What's the problem, folks ??
Are there some "copyright restrictions" for stream links ??

From the FAQ:

Why have some of my saved stations disappeared?
Radio stations sometimes change the URL (web address) of their streams; they may also stop broadcasting. To avoid the station database being polluted with broken stream links, the Yourmuze system regularly checks all station links. Streams that are unavailable for a period of time are removed from the database (and your 'My Stations' list).

If this has happened to you, you could try finding the correct source address from the station's website and resubmitting this to Yourmuze using add a new station.
