Yeah, good suggestion, freesey! I discovered the Mostly Classical net-radio channel via the Apple iTunes software a long time ago. The iTunes, and its Wintel equivalents, will give you quite a few classical net-radio channels that are out there, and all of them of course display what is being played.

Also, I highly recommend the net-broadcast of my local classical FM station: www.wrr101.com. IMO, the programming of WRR is unusually "sophisticated" as an FM station -- you aren't just forced into the "top-100" popular classical only. I continue to encounter the pieces that I've never known before through this FM station.
