OST 英文定义

OST: original soundtrack. A collection of music found in a particular video game, anime, movie, TV series, etc. Often referred to as a "music score" or simply a "soundtrack" in the U.S. For some reason, Japanese companies love adding on the word "original." In katakana, it is spelled "ORIJINARU SAUNDOTORAKKU." However, many Japanese will truncate that second word to "SAUNDOTORA." 摘自：http://www.ffmusic.info/glossary.html
