The radio blared from the car, and then, his song. This was the first time he'd heard it on the radio, and he was surprised. He was also surprised at the singer's delivery. He leaned back in his seat, grinning, as he pictured the look on his producer’s face when he heard this version. He started to sing along, completely out of tune, and drummed on the steering wheel, lost in his own little world. He cranked up the volume, then pulled over to the side of the road, letting the track run to its end, thoroughly amused by the whole experience.
