Song is a recorder of feeling

I don't know other people do experience the power of song. Sometimes, I did count those matters that were happened in past. In the my secondary shool and university life, there were a lot of special matters happen, those matters that gave me unforgettable feeling, especially those sad feeling. In every period of my life, I listen different songs. So when one unforgettable sad matter happened in the period that I was listening some songs; in future, everytime I listen again those songs, they will bring me back the feelings that as fresh as just happen!! I will continue to keep those 'special songs' that record my treasure feelings.
