O.s.t意思

"O.S.T." is an acronym that stands for "Original Soundtrack" or "Original Score Track." It refers to the music album containing the songs and background scores from a film, television show, video game, or other form of visual media. OSTs are often released separately from the media they accompany and can include a variety of music, such as instrumental pieces, theme songs, and songs by popular artists that were featured in the production. Fans of movies, TV shows, or video games often enjoy collecting OSTs as a way to relive their favorite moments from the visual media and to appreciate the music in its own right.
