Juketify

Right-clicking a jukebox with an empty hand opens a search screen. Typing a title and pressing enter looks the song up online, fetches it once, converts it and starts playback. Songs already cached on the host's machine play at once from the closest match, so later requests for the same track skip the fetch. A player holding a music disc still uses the disc as usual.

Playback is synced: everyone inside the hearing range hears the same track at the same point, and a player who joins mid-song or walks into range catches up instead of restarting it. The stop command halts the music for all listeners, the rescan option re-reads the music folder without a restart, and breaking the jukebox stops it too. The hearing radius defaults to 64 blocks and can be set from 16 to 128, though changing it requires a specific operator permission.

Juketify is a server-required mod with an optional client side. Installation needs Fabric API, and the server host must also have yt-dlp and ffmpeg installed and available on the PATH of their own machine. The mod is published for Fabric only, in its 0.2.1 beta for 26.1.2. Its license is Creative Commons Attribution Non Commercial Share Alike 4.0, so the code is not open source.
