What is a song?

Human thoughts are so varied.

But somehow people manage to find the exact song they want to use for emotion expressing.

And then all past doubts are vaporized.

And then all unsaid words are somehow delivered.

And then we believe this moment is made for this song.

Or this song is made for this moment.

Discovering it sooner or later, its effect will be less obvious.

Call it coincidence.

Call it clearance.

Call it the emotion we certain people all have.

Some poet expressed it in his way, and then we can use it to express more from it.

Music is miracle.
