This mod is no longer in development. I recommend using Music Triggers instead.

A 1.19.2 port of Vazkii's old Ambience mod found here: https://www.curseforge.com/minecraft/mc-mods/ambience-music-mod

The original description:

Ambience

Ambience is a successor (hell, it's literally built on top of it) to my, now discontinued, RuneTune mod. It's a mod that adds an environmentally aware soundtrack to minecraft.

In reality, that's a lie. The mod itself does not add any music, but it adds the ability for you to craft, using a config and mp3 files, your own soundtrack for the game, or just download a music pack and go from there.

NOTE: This mod is incompatible with mineTunes, as they both use the same library that requires access to the audio system.

I don't care! Just give me some music!

Ok, then. If you don't want to make your own music pack, pick one from the following.

Music Pack listing

More music packs will be added in the future. If you make one for personal use, consider uploading it to curseforge and telling me about it, so I can add it to the list and more people can use it!

How do I install these??

Watch this video.

Carrying on, if you're still reading...

Songs are picked using the in the following order:

Event Songs
Biome Specific Songs
Primary Tag Songs (using the Forge Biome Dictionary to categorize multiple biomes in one swoop)
Secondary Tag Songs (same gist)
Generic Song (if all else fails)

You can define all of these using the config file)

All the current events that can have a custom song:

Main Menu
Boss Battle
Underground (Y<50, no view to the sky)
Deep Underground (Y<20, no view to the sky)
High Up (Y>128)
Village (having at least 3 villagers in a 30 block range)
Underwater
Riding a Minecart
Riding a Boat
Riding a Horse
Riding a Pig
Night Time
Raining
Dying (less than 3 hearts)
Fishing
Wearing a Pumpkin Head
Being in the Nether (any biome)
Being in the End (any biome)
Horde (6 or more mobs withing a 16 block range)
Generic Song (this is used as a fallback, in case there's no song for the biome the player is in and there's no event that'll cover it, you MUST have this in your config or you risk a crash)

If there's an event you don't want to have a custom song (say you don't fancy the idea of having a night time song that overrides biome songs, you can just remove it from the config and it won't be used.

Here's an example of a config file, configured to use the RuneScape soundtrack. This makes use of every single event present in the mod.
