When there's something that you're passionate about and that has deep meaning for you, it's hard to imagine that it doesn't have a universal meaning for everyone and that everybody wouldn't like it. But there's pretty much nothing that everyone will like. I used to give out my radio show to people who, in hindsight, definitely didn't care. I understand now that people don't care or might not even have the time to invest in other people's obsessions. In fact your own interest in something might totally change over the years.
My own interest in soul music has been expanded via doing a radio show, as, over time, I can "get" or understand sounds that I didn't care about before. Now I like all sorts of soul music in all sorts of different styles and tempos from the early 60s to the late 80s. But people who, for example, are just getting into the music that I liked 10 years ago might not appreciate all the sounds I like now.
