Most of the music does not play at a matching volume in game, even the same tracks play with different volume based on the biome. Due to this, players need to adjust the volume inconveniently for each situation, this issue affects other dimensions too.

Steps to reproduce: (edited from MCPE-158157)

1. Locate biomes with different music like a plains, desert, swamp and mountain.
2. Let music cycle between different tracks without adjusting volume.

Expected behavior:
All music tracks are similarly mixed for volume, barring the normal dynamic range of the track.

Observed behavior:
Different tracks play at very different volumes.

Alternate steps:

1. Open
   C:\Program Files\WindowsApps\Microsoft.MinecraftUWP_1.19.202.0_x64__8wekyb3d8bbwe\data\resource_packs\vanilla_1.20.0\sounds\sound_definitions.json
2. Search the file for "music" to find the "music.game..." sections.
3. Observe the "volume" settings for the music tracks.

Observed result:
Alot of tracks are set to different volumes, the majority of the tracks with "wrong" volume are set to 0.1, 0.2, 0.3

Expected result:
The majority of the tracks should have their volume set to "1.0", with a few exceptions (based on java edition).

A simple way to fix this is by changing the volume of every music sound event on the json file (music.game...) to better match java edition, from what i know (correct me if i am wrong), only in a few specific cases the volume is set in java edition, making all tracks sound relatively the same in game.

The difference between java and bedrock values on the sound.definitions.json can be seen on this minecraft wiki page: https://minecraft.wiki/w/Sounds.json
