Music is life. Music defines peoples' experience on this planet. Name one time in your life that wasn't punctuated by the music you listened to at the time. When people are down, they listen to music that commiserates that emotion. When people are amped up, they listen to more upbeat, loud songs.
What SF can do better than anything else is show us the range of our possible futures, and what we can do to realize the good ones and avoid the nasty ones.
