Resource packs which previously defined "warped_forest" music no longer work in 1.21.110.24

Previously, it was possible to add a “warped_forest” entry to the music_definitions.json file to add music to the warped forest. The addition of the biome_music component in the warped_forest client biome file in 1.21.110.24 has broken this feature, since it sets the music definition to ““ (nothing) instead of “warped_forest”.

To Reproduce

1. Launch Minecraft 1.21.70 or earlier.

   1. Versions 1.21.80-1.21.100 are affected by MCPE-219051. Biome-specific music does not function properly in these versions, so they will not be able to reproduce the bug

2. Import and apply the attached sample resource pack, warped_forest_cat_music_disc.mcpack

   1. This resource pack causes the Cat music disc to play constantly in warped forests.

3. Enter a world in Creative mode with Cheats enabled.

4. Go to the Nether.

5. Enter a warped forest.

6. Set Music slider to 100 in Settings → Audio

7. Run the following command:

   1. /music stop

8. Wait a few seconds. Cat should start playing.

9. Observe that this shows resource packs can add music to warped forests by editing music_definitions.json in 1.21.100.

10. Close the game.

11. Launch Minecraft Preview 1.21.110.24 or later.

12. Repeat steps 2-7.

13. Notice that no music plays.

14. Observe that resource packs can no longer add music to warped forests by editing music_definitions.json in 1.21.110.24.

Expected Result

Resource packs that added music to warped forests continue to work in 1.21.110.24 and later.

Observed Result

Resource packs that added music to warped forests stop working in 1.21.110.24.

To Fix

Replace the “minecraft:biome_music” component in warped_forest.client_biome.json with this:

"minecraft:biome_music": {
  "music_definition": "warped_forest"
}
