Angel With A Shotgun

If Dean had been driving, they wouldn't have been listening to Sam's crappy radio station. If they hadn't been listening to Sam's crappy radio station, they wouldn't have heard the song. And if they hadn't heard the song, they wouldn't have heard the letter, and Dean would have never been able to kiss Castiel. Doesn't mean Sam's music taste doesn't still suck, though. (ONESHOT)
