MusicXCST

MusicXCST is a Fabric mod that adds writable custom music discs to Minecraft.

Use the CD Writer block to turn local audio files into playable Blueprint CDs. Give each disc a custom name, color, and pixel-art disc design, then play it in a jukebox. MusicXCST works for singleplayer worlds, LAN worlds, multiplayer servers, and modpacks.

## Features

• Writable Blueprint CDs
• CD Writer block and GUI
• Local audio upload and conversion workflow
• Custom disc names, colors, and disc designs
• Working advanced disc texture editor for custom Blueprint CD artwork
• Jukebox playback through MusicXCST's custom audio engine
• Server-side audio storage and ownership metadata
• Client audio cache with checksum validation
• Configurable file size, duration, storage quota, and per-player limits
• Admin commands for music library management
• FFmpeg setup options for audio conversion

Supported input formats include mp3, mp4, wav, ogg, flac, m4a, aac, webm, and avi. FFmpeg may be required for converting non-OGG files. If FFmpeg is missing, MusicXCST can guide the player through setup or allow OGG-only usage.

MusicXCST is useful for players who want personal music discs, server owners who want controlled custom audio, modpack creators, and developers building around custom music workflows.

## Requirements

• Minecraft 26. 1. 2
• Fabric Loader 0. 19. 2 or newer
• Fabric API
• GeckoLib 5. 5. 1 or newer

The mod should be installed on both client and server for multiplayer use.

## Audio Rights

MusicXCST does not include copyrighted music. Users and server owners are responsible for making sure they have the rights to any audio they upload, distribute, or play.
