# What<\/p>\n
SpindleMark is a quick way to add music discs to modpacks. Simply drop any Ogg Vorbis, XM, S3M, or MOD file into the new `music` directory in your game directory, and it will be scanned and discovered, appearing in a new creative tab. Discs get randomly generated colors, and the displayed author\/title are plucked right from the audio tags. Play length tracking is tick-accurate.<\/p>\n
# How<\/p>\n
Only one item is registered \u2014 the server is entirely unaware of what the music is, making for easy updates and quick prototyping. NBT-savvy users can make discs that play any sound event in the game. A simple F3+T will reload the music list.<\/p>\n
Module files may also be optionally compressed with BZip2 to save space. Why BZip2? Vanilla actually ships a library for decompressing it, and in my testing it’s the best compression algorithm available *without adding new code* for module files.<\/p>\n
As of 1.1.0, you can also add “built-in” discs via JSON files in the `music` directory. Let’s say you’ve always wished Biome Fest was available as a music disc:<\/p>\n
“`json
\n{
\n “artist”: “C418”,
\n “title”: “Biome Fest”,
\n “length”: “06:22.94”,
\n “sound”: “minecraft:music\/game\/creative\/creative1”,
\n “start”: “29.76”
\n}
\n“`<\/p>\n
`start` allows you to skip into the track, for things that have a long lead-in like Biome Fest that you would like to skip when being played as a disc.<\/p>\n
Here’s a pack of JSON files for adding built-in discs of every Creative and menu track.<\/p>\n

The name is meaningless \u2014 I wasn’t sure what to call this mod, so I looked up a glossary of vinyl record terms and picked the first one that sounded interesting. Apparently a “spindle mark” is a type of blemish on a disc indicating it’s been played many times and without much care.<\/p>\n","protected":false},"excerpt":{"rendered":"
