I really want to now the name of this song or this singer (blonde female singer).
The music video starts where we can see that the boyfriend is depressed and sitting in a bus alone going to work. In this scene the singer is in the bus too but he cannot see her.
Then he arrives at work and a female colleague is talking to him and trying to help him with the papers that fell out of his hands.
At the end of the music video, we realize that the singer is actually dead and her ghost is singing for her boyfriend to move on and to find love again.
I can remember only one word in the lyrics which is ” lullaby ”.
