SlimyRedstone

Well this is rendered useless (for the moment, I hope so) because you can't get set sounds added in a custom resource pack unless it is a mod (AFAIK).
We can only play sound already in the game

{
  "sound_event": {
    "sound_id": "slimyredstone:musics.chvrches.the_mother_we_share"
  },
  "description": {
    "translate": "slimyredstone:jukebox_song.chvrches.the_mother_we_share",
    "fallback": "[#] CHVRCHES - The Mother We Share"
  },
  "length_in_seconds": 191.5,
  "comparator_output": 1
}

{
  "sound_event": {
    "sound_id": "slimyredstone:musics.chvrches.the_mother_we_share"
  },
  "description": {
    "translate": "slimyredstone:jukebox_song.chvrches.the_mother_we_share",
    "fallback": "[#] CHVRCHES - The Mother We Share"
  },
  "length_in_seconds": 191.5,
  "comparator_output": 1
}

I modified the JSON file to @haykam's recommendations, and it doesn't work.

Although, it only outputs an error (completely from the previous one) when executing a command with the custom data.

/give @s stick[jukebox_playable={song:'slimyredstone:musics.chvrches.the_mother_we_share'}]

/give @s stick[jukebox_playable={song:'slimyredstone:musics.chvrches.the_mother_we_share'}]

I hope I didn't misunderstood something when writing the code.
P.S: The song is playable through the playsound command so I don't think I messed up adding it in the resource pack

I thought I was going mad, I was making datapack/resource pack, and I was only getting errors while everything was in order.

I hope this is just an oversight, because it is a really cool feature.

Re: Dhranios

Sadly, it's a bit annoying when I'm using this behavior to, for example, fill a space with a specific block only when there is a support block.

For that particular case, I finally used carpets as they work as intended.

You have lag issues, that's not a bug 

English please

Yes, it sound a bit like MC-117449

I don't think so, I can do fully white armor in other versions
