Music . . . the heart's greatest librarian.The average song is three and a half minutes long; those three and a half minutes could lead to a slow blink, a glimpse of the past, or catapult the soul into heart-shattering nostalgia.At the height of my career, I had the life I wanted, the life I'd always envisioned. I'd found my tempo, my rhythm. Then I received a phone call that left me off key.You see, my favorite songs had a way of playing simultaneously. I was in love with one man's beats and another's lyrics. But when it came to the soundtrack of a life, how could anyone choose a favorite song? So, to erase any doubt, I ditched my first-class ticket and decided to take a drive, fixed on the rearview. Two days. One playlist. And the long road home to the man who was waiting for me.
