SpindleMark

SpindleMark is a convenient solution for quickly adding music discs to Minecraft modpacks. Simply place any audio files in Ogg Vorbis, XM, S3M, or MOD formats into the new music folder created in the game's root directory. The system will automatically scan these files and add them to a special creative mode tab. Each disc is assigned a random color, and information about the artist and track title is extracted from the audio metadata. Playback duration tracking is accurate to the game tick level.

How It Works

The mod registers only one item—the server has no information about the music content, which simplifies updates and speeds up the development process. Experienced users familiar with NBT tags can create discs that play any in-game sound events. To update the music list, simply press F3+T.

Module files can be additionally compressed using BZip2 to save space. Why BZip2? Because the standard version of Minecraft already includes a library for unpacking this format, and during testing it showed the best compression results without the need to add new code.

Starting from version 1.1.0, it became possible to add "built-in" discs via JSON files in the music directory. For example, if you've always wanted to have Biome Fest as a music disc:

{
    "artist": "C418",
    "title": "Biome Fest",
    "length": "06:22.94",
    "sound": "minecraft:music/game/creative/creative1",
    "start": "29.76"
}

The start parameter allows skipping the initial part of the track, which is especially useful for compositions with long intros that you want to exclude when playing through the disc.

Creation History

The mod was originally developed for organizing custom music at booths during the BlanketCon 23 event!

The name "SpindleMark" has no special meaning—the author couldn't decide on a name for the mod, so they consulted a glossary of vinyl record terms and chose the first one that seemed interesting. It turned out that "spindle mark" is a type of damage on a disc indicating it has been played many times without proper care.
