A soundtrack is a collection of music that accompanies a film, television show, or video game. It can include original scores composed specifically for the production, as well as pre-existing songs that enhance the narrative and emotional impact of the scenes. Soundtracks play a crucial role in setting the tone and atmosphere, often becoming iconic in their own right. In addition to enhancing the viewing experience, soundtracks can also be commercially successful, leading to chart-topping albums. Notable examples include the Titanic soundtrack, featuring Celine Dion's "My Heart Will Go On," and the Guardians of the Galaxy soundtrack, which showcases classic hits from the '70s and '80s.
