Music has the power to stop time. When I listen to songs, I'm transported back to the moment of their birth, which is sometimes even before the moment of my birth. Old songs, rock or soul or blues, still connect with me because the human emotions in them, whether jealousy or rage or hope, are recognizably similar to the emotions that I'm feeling now. But I'm feeling all of them, all the time, and so the songs act like a chemical process that isolates certain feelings at certain times: maybe one song helps illuminate the jubilation and one helps illuminate the sorrow and one helps illuminate the resignation. Music has the power to stop time. But music also keeps time.
