Charmonium: adds ambient sound and additional music tracks to Minecraft. It is a client-only mod and does not require Charm to be present on the server. However, if Charm is available, then this mod gets a little smarter. ModMenu and Cloth-Config are also supported.
This is a Fabric version of Charmonium for Minecraft 1.17. If you are looking for the Forge version of Charmonium, it's in this repository.
