What Does International Standard Recording Code (ISRC) Mean?
An International Standard Recording Code (ISRC) is a universal standard of identification of soundtracks and music video recordings. The ISRC was first introduced in 1986 and then was later updated in 2001. This standard allows unique credentials of a sound recording and acknowledges the existence of music videos. Various artists get their work identified by ISRC to avoid theft and reserve copyright.
Techopedia Explains International Standard Recording Code (ISRC)
An International Standard Recording Code is specific for a particular recording to secure copyrights of music composition and lyric contents. It is now common among artists to get their work registered under ISRC to maintain a standard and reserve due rights in case of illegal use of their work. Since the ISRC is particular for composition and lyrics, each new version of a song by the same artist requires a new ISRC number. This uniqueness is maintained within different editions of the same song.
