MARY, DID YOU KNOW ?
T-070116700-1 is an International Standard Musical Work Code (ISWC) that uniquely identifies the musical composition "MARY, DID YOU KNOW ?". ISWCs are defined by ISO 15707 and managed by CISAC. Unlike ISRCs which identify recordings, an ISWC identifies the underlying song — the melody, lyrics, and arrangement.
