I have decided to rewrite the entire bug report so it's more clear. The bug that I have discovered a few updates ago is for music. I also made my own music resource pack with more added songs to biomes and with my knowledge, pretty much every biome specific soundtrack is glitched. Instead of hearing songs like Ancestry and Deeper in the Deep Dark, you get something that plays as the default biome. For example, for the Deep Dark biome, it should be running “music.overworld.deep_dark”. And instead, it plays the old default music and uses “music.game.wild_equal_chance” or anything that isn’t targeted for one biome. Songs that are for Creative mode, The menu music, and the Nether are not effected by this. I don't think so anyways. As for the End dimension, it just has one soundtrack so. Another detail is that songs take so much time to play another song instead of the usual 1 minute wait time, like if it was Java. I'm also so glad that I'm not the only one noticing this bug that is very hard to notice, unless you are very familiar with the soundtracks for specific biomes. Sometimes the music comes back as normal after playing for awhile, but this happens very rarely.
Steps to Reproduce
Turn your Music audio setting up to 100.
Enter a world in Survival Mode with Cheats enabled.
Go to a Deep Dark biome. This biome has easily recognizable music because only two tracks can play: Ancestry and Deeper. Ancestry is recognizable because it begins with crackly static and a repetitive, creepy synth. Deeper is recognizable because the beginning sounds almost “shiny” (cannot think of a better description).
Wait in the Deep Dark biome.
Observe one of two things occurs:
A song that isn’t Deeper or Ancestry plays. This usually happens for me if this was the first world loaded after launching the game.
No song plays at all. This usually happens for me if a world was previously loaded and exited before entering this world. Deep Dark songs are configured to play with silent periods of only 3-9 seconds between songs, so 60 seconds is plenty to confirm this situation.
Expected Results
Biome-specific music plays as usual in 1.21.90.
Observed Results
Biome-specific music does not play correctly in 1.21.90.
Notes
This issue is most likely related to the new “music_definition” feature that was added to all client biome files in 1.21.80. This feature is not present in any of the vanilla biome files, which may be the source of the issue.

accidentally made duplicate posts and they marked both of them as resolved on my end so hopefully this post will actually get the bug fixed
I am getting this bug as well in 1.21.100, I'm currently playing on a Xbox one and went to multiple biomes with biome specific music tracks but only random music that aren't suppose to play in those biomes played instead (Ex. in the swamps songs like left to bloom or Clark plays but not the music that is supposed to play there). The only time it did play the proper music was the first song loading in to the world but after that it was just other music.
I can confirm, playing on my PS5, most recent update version as of 07/29/25, this bug is effecting my world. I don''t know about other biomes yet, but deep dark/ancient city music is gone. Right down to when you are setting off shriekers. The times you set them off before the the warden spawns and you get the darkness effect, you get like a amplified, echoey sensor chirp normally and a basey thump. Those effects are gone as well.
Updated PS4 Minecraft 1.21.100. I cant listen to Deeper at Deepdark.
I’ve not listened to it for 3 months .I wish this bug is resolved next update.
In 1.21.110.24, Mojang added the biome_music definition to all Nether biomes and the normal roofed forest. This has not resolved the issue because all the following biome groups are still missing the component:
Swampland (all)
Peaks (all)
Meadow
Grove
Snowy Slopes
Cherry Grove
Birch Forest (all)
Roofed Forest Mutated
Forest
Flower Forest
Mega Taiga (all)
Redwood Taiga (all)
Mesa (all)
Desert (all)
Lush Caves
Dripstone Caves
Deep Dark
For this issue to be resolved, all these biomes need the correct biome_music configuration. I have tested and confirmed personally that adding the component with the right definition to these biome files fixes the music issue.
While I don’t know too much about the coding involved, I too can confirm that the biome music has been broken for a few months now. Hopefully this issue gets Mojang’s attention soon.
August 15 bug has not been fixed yet. Hope it gets fixed soon. Trouble shooting steps I attempted:
Deleting and reinstalling the game
Fresh survival world without cheats
Fully restarting my Xbox
Ensuring volume settings were correct
Setting off shriekers until the warden spawned
And nothing fixed the problem
Can confirm. I am experiencing this issue in 1.21.90.
