I actually used to have my stereo hooked up to cable radio in my teens... other than having to re-learn all the frequencies, it was amazing quality. I seem to recall that even CHED (the teenbopper radio station of choice in Edmonton during the 80s, now an all-talk station) had an FM cable feed.
My current stereo gets awful reception, even with the wire antenna strung halfway toward the window, so I was actually considering a three-way splitter and trying cable out... guess that won't be happening now.
