Music influences people in several important ways: 1) Popular songs often have catchy tunes, strong lyrics, and well-structured sounds that resonate with listeners on important life topics or personal experiences. 2) Music plays a key role in movies by eliciting emotional responses from audiences and impacting how scenes are perceived. 3) People use music to relax, be inspired, or express their own feelings and experiences. The Beatles hugely shaped culture through their influence on fashion and hairstyles. 4) Historic charity events like Live Aid demonstrate how music can unite people worldwide around important causes.
