Music

What if music poured from the skies? Like the wind blows, the sun shines and the rain falls from the skies? Maybe like the background score in a movie would be for its characters (If they were for real and could hear it).
Imagine you going for a walk, all alone, on a dark night and there is music, huge speakers hidden all across the sky, the volume faint, very faint but still there. It could be a sad song if you were sad and a happy song if you were happy or maybe vice versa.
