What Can a Song Do To You

Music from an open window
Music, sudden and fleeting
Ordinary music, in an ordinary street
Why does your heart start beating?

What can a song do to you?
Can it waken a memory sleeping?
Can it call back a day, when your heart fled away
Into somebody else's keeping?

What can a song do to you?
Can it bring back a spring in December?
Can it make, with each note, such an ache in your throat
That you find you can still remember?

For the past is a house full of treasure
And there lies, buried deep in the storm
Every smile, every tear, every pleasure
And a song is the key to the door

What can a song do to you?
Can it kindle the flame that was dying
Till it burns once again, with its joy, with its pain
And your heart's of a sudden crying?

Oh, I know, yes, I know, now I see
What a song has done to me
