An ISWC identifies a musical work (the underlying composition — melody, lyrics, arrangement). An ISRC identifies a specific sound recording of that work. One ISWC can have many ISRCs — for example, the original recording, a remix, a live version, and a cover would each have their own ISRC but share the same ISWC.
