We all need rewards of some kind of other, and when we don't get a reward from the person or entity we desire one from, most of us seek out other means. Perhaps that's why some people spend inordinate amounts of time developing enough technique to play in a way that can be self-rewarding. Perhaps that's why some people spend inordinate amounts of time writing music: hours and hours of time for the reward of a minute or two of music that works. Some of us pretend to exist on self-rewards. Sometimes we fool people. Sometimes we can even fool ourselves, but the deception doesn't last.
Most of us need rewards on a regular basis. Perhaps we crave cadences, because each one is a reward. Each cadence is a journey (of varying length and landscape) from instability to stability. Perhaps that's why tonality has survived for so long, and why it will continue to survive--even to thrive.
Rhymes are rewarding. Snappy rhymes plus music with strong cadences equals popular music. And there's nothing wrong with liking music that is popular, or music that once was popular. Consider Verdi, consider Gilbert and Sullivan, consider George and Ira Gershwin, and consider Cole Porter.
If I listen to well-performed tonal music when I'm feeling down, I magically feel a bit better, at least while I'm listening.
