Your college radio station sounds like it was more fun than mine (early 1980s). I was a DJ for awhile, and the station manager used the word "format" like a holy mantra and disallowed anyone playing anything that could be considered "heavy metal" or "punk" or whatever until late at night.
Days were filled with top-40 pop. The only time we could really let loose was late on weekend nights, but then no one was listening.
I used to drive them crazy by calling the station during the day and requesting "Rat Salad" by Black Sabbath all the time.
Yeah for years we had alternative rock all day, with the
harder/weirder stuff in the afternoon (Suburban Beat);
specialty shows for jazz, blues, reggae, etc. We still do a lot of interesting stuff. I actually
do their website and will be doing a blues show there
today at noon (sorry, we don't streamcast!)
