As a music enthusiast, I've come across a plethora of songs featuring the word 'sound' in their title or lyrics. One that immediately springs to mind is Simon & Garfunkel's classic, "The Sound of Silence." This hauntingly beautiful song uses 'sound' in an ironic sense, highlighting the profound silence we often find in our bustling lives. Another notable example is Adele's "Rolling in the Deep," where 'sound' is mentioned in its powerful chorus. These songs not only feature 'sound' prominently but also use the concept to convey deep emotions and thoughts.
