On bRadio, I haves tried completing the urls and have copy and pasted some from members with no luck.
The couple of station that I have found that I have previously accessed with Sony Hap and Lumin, I do find the sound from bRadio/MM to be more detailed, fuller in sound and more enjoyable, even when when using the other units as transports. Sound from within mm is better to my ears.
I have internet radio on all day. Not sure if this is possible, but as a possible solution for the updated software, but have a look at TuneIn and Lumin’s implementation. One creates a free Tunein account, Lumin creates a link in it’s software and one just updates one’s system. Tunein has a wonderful search engine, looks great,access to sports, blogs etc and is 100% responsible for programming. So, you would only have to creat the interface. Not sure of licensing costs.
