OST, or Original Soundtrack, refers to the collection of music specifically created for a film, television show, or video game. These soundtracks often include both instrumental scores and songs that enhance the emotional and narrative aspects of the visual media. Composers like Hans Zimmer and John Williams are renowned for their contributions to OSTs, creating memorable pieces that resonate with audiences. In addition to enhancing the viewing experience, OSTs can also stand alone as musical works, allowing fans to enjoy the music outside of its original context. Many OSTs have gained popularity, leading to chart-topping albums and even awards, such as the Grammy Awards for Best Compilation Soundtrack for Visual Media.
