This is my permanent radio station (well, for now at least - I have about 6 favorites preset on live 365). You can pay for this service, too - I think it's $14.95 every 3 months - you get commercial free and CD quality hi def sound.
Pat (the guy that runs this station) takes requests, and gladly accepts oddities that fall under the Queen umbrella. I sent him a copy of Love of My Life by a woman from Brazil - haven't heard it yet, though.
I recently wrote to him asking for Jeffrey Osborne's 'Stay With Me Tonight' - within a day or so, it became part of the rotation.
It's really good if you want to hear an odd Smile song, or live stuff. He's also been adding a lot of Brian and Roger solo stuff (demos, extras that didn't make it to the albums, etc.)
Really - check it out. You won't be disappointed.
