As a regular listener to I-radio, I'd recommend at least putting your name to a petition fighting against the fee hike.
www.radioio.com has information about a petition called "Save the Streams," that I have already added my name to. And yes, this did come up previously, though the hike was cancelled (I don't remember why).
As a jazz buff, I value any music system that brings me jaz, and I-radio and sat radio are the two best sources of jazz I know.
