"Fight" was the Moldovan entry in the Eurovision Song Contest 2007, performed in English by Natalia Barbu. The song was written by and composed by . The song is a metal-based number, comparable to Within Temptation or Evanescence in sound. Barbu sings about the need to "fight" in order "to face this cruel world", and sings that this is in fact the only way to get ahead. The melody line is provided by a violin, which Barbu herself plays in the video, as well as playing in the live performances. Barbu laughingly said that even though she couldn't play live at Eurovision (the rules forbid this), the background track violin is played by her and that it was actually a very easy part since she has been playing since she was seven years old.
