I am trying to express my emotions with this. Some may sound very horrible to your ears, those parts are to represent anger and stress. This song is like the timeline. Notice how most of the "anger and stress" is at the end of the timeline. Then at the very end, you hear a music box, it means that you are remembering the good days of the past. The rest of the music box is at the beginning of the timeline and means, "happiness and joy."
All by me. I used a program to make the song.
