Meaning

OST stands for "original soundtrack", the music made for a drama, film or other work. An article from the Korea Creative Content Agency (KOCCA) says K-drama OSTs draw viewers into the scenes and the actors' emotions and keep the drama in mind long after it ends. Idols sing drama OSTs too: a 2010 Seoul Shinmun report said that miniseries OSTs of the time were practically a stage for idol stars, noting that 4Minute, SHINee and SUPER JUNIOR sang the theme songs of MBC's Personal Taste, SBS's Prosecutor Princess and KBS2's Cinderella's Sister. A hit drama's OST reaches a large audience over two to three months of broadcast and, once the drama is exported, keeps selling for years.

Usage

Paired with the title of the work: "the Hotel del Luna OST". Streaming releases may come as numbered singles such as "Pt. 3".
