He was driving, late at night, the city lights blurring past. The radio, his only companion, buzzed with static. Then, the signal cleared, and the familiar opening melody filled the car. His song. He turned the volume up, his hand hovering over the dial. Another singer, another voice. The arrangement was different, faster, upbeat.

He pulled over to the side of the road, the lights of the city seeming to recede. The words were the same, but the feeling was gone. He felt a deep ache inside, a emptiness that echoed the rhythm of the music. He closed his eyes, and the sound washed over him, a relentless tide of memory. The tears came, unbidden, streaming down his face.
