Login Music
Login Music plays a song when a player joins a world, with MP3 files read from a folder in the game data directory.
What it does
On join, the mod starts a track chosen from the music files the server or player has placed in the Login Music folder under the data directory. Each player can be given a different track based on their name or UUID, and lyrics can be shown while the song plays. Supported audio is MP3, and the audio backend loads the files when the game starts.
Configuration is handled in a JSON file, and entries must follow the format's rules when more are added. A server's own config file takes higher priority than the client's and overrides custom settings. The settings can also be opened from the main menu through Cloth Config, and the API is installed alongside the mod.
Login Music is released under the MIT License and is open source. The source code and issue tracker are public. Files are published for Forge and NeoForge, with 1.2.7 as the latest build for each, covering 1.20.1 and 1.21.1.
