Have you ever just been driving in your car and you hear those first few notes and all of a sudden you are overcome with emotion.  You begin driving with one hand, the other is now a microphone or a very vivid gesturer of your feelings.  Your voice begins without you realizing, singing along with all of the memories of past best friends, boyfriends, girlfriends, and imaginary friends swimming in front of your eyes.  Then you realize that you are crying as you sing at the loudest your emotion allows. Two hands on the wheel now, clinging while you say whoa-oa-oa. Then your hand returns, holding up a hush finger to your memory, "Don't speak!" you wail.  The words all come to you and for about five minutes you are overcome.  Wherever you are, red light, freeway, parking lot, side streets, or waiting for the song to end before you leave your car because you are at your destination, you sing.
