Turn on a popular music station (something not dedicated to a specific theme, such as classic or concert music), and listen for 30-60 minutes. Count how many songs you hear that do not feature love, sex, or related topics (such as partying).
I’ve tried this a few times. So far my record high score is one point. And I’m not entirely sure I can count that one.
I’m not entirely sure what this says about the music or the audience or the people who decide what ends up on the radio. It just seemed like an interesting pattern.
