why should the devil have all the best tunes

The phrase "why should the devil have all the best tunes?" is a rhetorical question that questions the notion that virtuous or morally upright individuals should not engage in or enjoy entertaining or pleasurable activities. It suggests that there is no reason for only those with negative intentions or behaviors to enjoy the pleasures of life, and that good-natured people should not restrict themselves from experiencing enjoyment and indulgence. The phrase is often used to challenge traditional or puritanical beliefs that associate certain activities or forms of enjoyment with immorality or sin.
