Songs that are placed in TV shows and Films are used to enhance plot lines. Typically the lyric of the song, if the song is a vocal song, will have a correlation with what is happening in the story and the characters in the scene. Central to almost all stories are relationships. Whether someone is falling in love, falling out of love or longing for love, just like in our real lives, relationships play a big role in both TV shows and Films. It goes without saying then that there are a lot of needs for songs about relationships. There are of course many exceptions, just as there are when it comes to the styles of music being placed, but there will always be a need for relationship songs.
