Music Decoy solves a persistent macOS issue where pressing the Play button launches Music instead of your preferred media player. Version 1.1+ allows users to configure terminal commands redirecting play events to apps like Spotify, stopping Music from hijacking media controls when no other app is playing audio.

The problem originates from the rcd daemon that checks for active audio playback. When no app is playing, it defaults to launching Music. While completely disabling rcd exists as an alternative, it also removes keyboard media control functionality, making Music Decoy a more surgical solution to a specific system annoyance without broader side effects.

For those seeking alternatives, noTunes monitors launched apps and kills Music automatically, though it uses minimal CPU resources. To quit Music Decoy—which lacks a dock or menu icon—users must use Activity Monitor or the terminal command `killall 'Music Decoy'`. The tool provides a simple fix for a system-level behavior without complex workarounds.
