Final answer:
Sweet Soul often describes a style of music or art that is emotionally expressive and deeply moving, best exemplified by artists like Sam Cooke. It encompasses themes of love, sorrow, and human spirit that stir emotions and inspire change.
Step-by-step explanation:
The term Sweet Soul within the context of music often refers to a style that is smooth, heartwarming, and emotionally expressive. Sam Cooke, known as the 'King of Soul', epitomizes this style with his melodious voice and meaningful lyrics that often address themes such as love, joy, sorrow, and the struggle for equality.
Cooke's work not only entertained but also inspired change during the civil rights movement. In a broader artistic sense, Sweet Soul can relate to any expression that deeply stirs the emotions and appeals to the nobler aspects of the human spirit, akin to the words of the poet who speaks of a 'countenance in which did meet Sweet records, promises as sweet.'
This reflects the multifaceted nature of soul, which can also be described as the essence of a person or an artistic work that can move and inspire others.
