Of course I made a bug report without trying everything. This bug only happens when you don't close and re-open minecraft!

I'm making some custom songs for a game that I'm making, and I'm replacing the underwater songs to do so. There are 3 songs, but only 2 of them work. For some reason, replacing "shuniji" with another song won't do anything, and the original song will play. The other 2, Dragon Fish and Axolotl, work fine.

I even tried swapping the custom music replacing Dragon Fish with the file replacing Shuniji, but that still didn't work. The music that was working for Dragon Fish didn't play anymore, but the file that was replacing Shuniji worked.

And it isn't only that one song, either. I tried replacing other songs before replacing the underwater songs, and some of those didn't work either.

Sorry if this is confusing at all, I don't really know how to explain it better!

Steps to reproduce:

• Get a blank resource pack
• Create a file in the "sounds" file and name it "music"
• Create a file in the "music" file and name that "game"
• Create a file in the "game" file and name it "water"
• Add 3 .ogg songs and name them "dragon_fish", "axolotl", and "shuniji", or just replace shuniji.
• Load the resource pack into a world, and use this command:

/playsound music.game.water @s

• Notice how the song that you used to replace "shuniji" doesn't play, but it only plays the default sound.

Observed results:

The custom music file for "shuniji" doesn't play, and instead plays the default song.

Expected results:

The custom music file for "shuniji" should play, and not the default song.

This isn't the only song either! Trying to replace the credits song or the Soulsand Valley song won't work either.
