The use of the audio track by Al Green "I'm so tired of being alone", in my opinion is a powerful dramatic tool that will heighten audiences sense of the characters mind state and add to the mood of the dramatic ending.

The music is diegetic, so it gives the scene a more authentic feel, this is a style choice that is used throughout the film to create the characters world. The song is a clear representation of the characters feelings and illustrates the extent of his loneliness. It also juxtaposes the ending of the film, the soft soulful sounds of Al Green are in stark contrast to the shocking images of the final shots when we realize he is psychotic and has a female prisoner.
