this is not conform when using a streaming box or external players.
No, they deliberately and actively exclude external software players and streaming boxes
Its not good for the listeners but when theses stations means that this is a good thing for cost saving??
I would strongly doubt that in the long term this business model will be good for the stations - they try to swim against the current, as obviously internet radio devices are selling very well. Apart from that most listeners will click away the banner window immediately, and my Firefox for example doesn't even show the advert, just an empty window
I think that most stations, which have links for external players can be played by the soundbridge.
Unfortunately quite a lot do not play, either because they are "geo-locked" or offer incompatible streams, for example Real Audio, Flash or RTSP-streaming
there are hundreds of stations in the world which will be discovered.
There are more than 7000 to be discovered within Radio Roku
