What is ISWC T-011801870-4?

T-011801870-4 is an International Standard Musical Work Code (ISWC) that uniquely identifies the musical composition "RELAX". 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.

This work has 36 recordings (ISRCs) associated with it. Each recording represents a distinct version — such as the original, a remix, a live performance, or a cover — that shares the same underlying composition.
