We come to love some songs by accident. The first 98 times we hear it on the radio, the synth sounds cheap and grating, the lyrics idiotic. Then that 99th time, we happen to be sitting with the right set of people, driving at the right speed, and the music blossoms before us. Forever after, we hear a completely different song.
The most effective aphrodisiacs are repetition and context.
Of course, it works the same way with books, movies, and foods. Reality TV shows and poetry and long-distance running. New cities, new jobs, new challenges.
