For me,music is one of the greatest way to show your emotions... ...As those video proves.

The song is about a man who was created via chemical experiment and never had a mother. He's sad, because he doesn't have any family. He's also angry. Kinda crazy. Wants to kill the mother, whom he doesnt have, but he wants also love, from the same mother. So kind of emotional and psychological song.

In this one,the song talk about the story of a boy & a girl.The girl is dying or leaving and she wants to tell him but she cannot find the courage to tell him so she spends the last of her time with him.
