BGM Fields
by oj1755
Players who want ambient music tied to a region can place Realm Blocks in BGM Fields, which creates zones that switch tracks when a player enters them.
What it does
Each Realm Block defines a zone with a radius of up to 300 blocks and an optional vertical range, so a realm can be limited in height as well as in its horizontal extent. Zone rules are set on the server and applied to every player, and a realm is edited only by its owner, or by operators with permission level 2. Track switching runs from a single-track playlist, and tracks are referenced by Sound Event ID in the form namespace:path.
The mod sends .ogg audio files over the network. Actual audio is delivered through a client resource pack that the server pushes to each player when they join, and BGM Fields generates that pack automatically in a folder it creates. The pack can be reloaded in-game with the Reload button or with F3+T. The author notes that a sounds.json file has to be written by hand. The mod has to be installed on both the server and the clients, and its config keys sit in the Forge common config.
BGM Fields is published for Forge only, across six release versions 1.20.1 – 1.20.6, with 1.4.0 for 1.20.6 as the latest file. Installation covers the server and each player's game.
Key features
Server-authoritative realms
Realm zones are defined and enforced on the server, and the server tells nearby clients which settings apply.
Realm Vision visuals
A visual module can apply fog, a sky-only tint, particles and colored precipitation inside a realm, with its color used for the effects.
Glowing boundary ring
An optional ring marks the edge of a realm, visible from inside and outside, so players can see where a zone starts.
Disguised Realm Blocks
Owners see the real Realm Block, while other players see it disguised, so zones can be placed without advertising them.
Craftable Realm Block
The Realm Block is a craftable item that is placed to create a realm, with its radius capped at 300.

What the author says
This mod does not send.ogg audio files over the network. Music is referenced by Sound Event IDs; you provide the actual audio via a client resource pack (per-player) or a server-pushed resource pack. Multiplayer: install the mod on both the server and all clients.
