An imaginary friend

Music has the ability to provide company and comfort. People tend to listen to sad music more often when they are in emotional distress or feeling lonely, or when they are in introspective moods. Sad music can be experienced as an imaginary friend who provides support and empathy after the experience of a social loss. The listener enjoys the mere presence of a virtual person, represented by the music, who is in the same mood and can help cope with sad feelings.
