MusicXCST

Players use the CD Writer block, a GUI block, to turn a local audio file into a playable Blueprint CD. Audio files in mp3, mp4, wav, ogg, flac, m4a, aac and webm can all be imported as input. Conversion of non-OGG files needs FFmpeg; if FFmpeg is missing, the mod guides the player through its setup, and OGG-only usage remains possible without it. Each disc can be given a custom name, a color and a pixel-art design made in an advanced disc texture editor.

Playback runs through the mod's own audio engine, and the jukebox plays the finished discs. Audio is stored on the server with ownership metadata, while each client keeps a local audio cache validated by checksum. MusicXCST runs in singleplayer, on LAN, on multiplayer servers and inside modpacks, and it fits personal music libraries, server owners who want custom music under their control, and modpack authors or developers who build custom music systems.

The mod requires Fabric API and Geckolib. It is published for Fabric only, for 26.1.2 alone, and runs on client and server, so the server and every player need it.
