Once, I inadvertently cued up a song I didn't mean to play. By mistake, I ended up playing "Wooly Bully" by Sam The Sham And The Pharaohs on KCOU. It was a big hit in 1965, but that song has always grated on me. It was the only time I ever apologized for playing a song on the air that I didn't like. On a commercial station, I never would have done that. On a noncommercial college station, however, I was able to express my dislike for a song.
It was liberating, for a moment, not to have to be objective.
