From euphoria to misery, music has the ability to change people's minds and lives. With help from 蜜芽传媒 Radio 4's Claudia Hammond, Steve investigates the science behind what makes our brain sing.

He tells Steve how to write a love song, what should come first, the music or the words and if there is a typical way he would compose a song of love.
