THC - The Harmonic Client
by incold
THC - The Harmonic Client is a Fabric and NeoForge client mod that turns music playback into animated visuals, a HUD media player and a shared listening party.
What it does
Installed on the client, THC reacts to the music a player hears and draws it as particles and geometry. Visualizer styles include bars, waveform, oscilloscope, dot, sphere, network, rain and float, and the HUD shows track information, cover art, progress, queue state and playback controls. A lyrics widget scrolls the words alongside the song, and a song queue prepares upcoming tracks automatically.
Players can request songs directly, and a listening party system lets a group join with a party code, set permissions for members and share a queue. Players can also mute or lower the music of other players in the party. Color themes come with presets, a color picker, RGB and hex input, opacity controls and separate color slots for particles.
The mod is released under the Apache License 2.0, but it is not open source. Files exist for Fabric and NeoForge, with builds covering 1.21.1 – 26.2 across five release versions. The latest Fabric and NeoForge files are 0.2.1 for 26.2, published 2026-08-26. Only players need the mod for its visuals; a server can run it to add features but does not have to.
