• Includes play/pause, previous/next, Single Once, Loop One, Loop All and Shuffle.
• Adds private headphones, moving nearby boombox playback and parrot/allay reactions.
• Supports sided hopper automation, optional instant redstone pressing and output comparator feedback.
• Captures a tuned note block as a single-note disc using the game's existing instrument sounds.
• Includes original assets, survival recipes, recipe discoveries, configuration and English localization.
• Fixes client sound-hook compatibility, cancelled stream cleanup, reduced playlist capacity enforcement and final-disc playback cleanup.

Requirements: Minecraft 1.21.1, Java 21, Fabric Loader 0.16.14 and Fabric API 0.116.6+1.21.1. Install the mod and Fabric API on both client and server.

Validation: 27 GameTests, 16 audio-stream checks, 95 Minecraft Ogg decoder comparisons and headless production client linkage passed. Standard Gradle execution, normal dedicated-server startup, live GUI/audio and connected multiplayer remain unverified because the development environment blocked those checks. Broadcast synchronization is approximate; elapsed song position does not persist across logout or server restart.
