Music/Jukebox Disc

Modern (Recommended)

Create the disc item

Create a new item in your config

info:
  namespace: my_sounds
items:
  song_1_disc:
    display_name: "Song 1 Disc"
    graphics:
      texture: item/song_1
    jukebox_disc:
      song: my_sounds:song_1

As you can see I added a special property called jukebox_disc. This allows putting the item into the Jukebox.

name

The sound to be played, in this example my_sounds:song_1.

Jukebox song sound

In this case put the sound file in contents/my_sounds/sounds/song_1.ogg.

info:
  namespace: my_sounds
sounds:
  song_1:
    path: song_1
    settings: # Optional
      subtitle: "Song 1 Disc" # Optional (No default value)
      volume: 1.0 # Optional (Default value: 1.0)
      pitch: 1.0 # Optional (Default value: 1.0)
      weight: 1 # Optional (Default value: 1)
      stream: true # Optional (Default value: false)
      attenuation_distance: 10 # Optional (Default value: 16)
      preload: true # Optional (Default value: false)
    jukebox:
      enabled: true
      description: "Song 1"
      comparator_output: 15 # Optional (Default value: 15)

As you can see I set the jukebox property. This enables this sound to be used in the new Minecraft 1.21.1+ jukebox component.
