What are some examples of connotation being used in a song?

In songs, connotation plays a significant role in conveying deeper emotions and themes. For example, in "Firework" by Katy Perry, the term "firework" connotes feelings of empowerment and potential, suggesting that everyone can shine brightly. Similarly, in "Hurt" by Nine Inch Nails (and later covered by Johnny Cash), the Word "hurt" not only refers to physical pain but also evokes deep emotional suffering and regret. These examples illustrate how connotation enhances the emotional impact of the lyrics.
