New Music disc without music

Hello, i want to make a new music disc but when i put the disc in the jukebox, i don't have the music

Here my registry for the sound events:

public class ModMusic {
    public static final DeferredRegister<SoundEvent> SOUND_EVENTS =
            DeferredRegister.create(ForgeRegistries.SOUND_EVENTS, bomod.MOD_ID);

    public static final RegistryObject<SoundEvent>  BETRAYAL =
            registerSoundEvent("betrayal");


    private static RegistryObject<SoundEvent> registerSoundEvent(String name) {
        return SOUND_EVENTS.register(name, () -> new SoundEvent(new ResourceLocation(bomod.MOD_ID, name)));
    }
    public static void register (IEventBus eventBus) { SOUND_EVENTS.register(eventBus);}
}

Here my registry for the item music disc:

   public static final RegistryObject<Item> BETRAYAL_DISC = ITEMS.register("betrayal_disc",
            () -> new RecordItem(1, () -> ModMusic.BETRAYAL.get(),
                    new Item.Properties().tab(ModCreativeModeTab.BOMOD_TAB)));

And here my sounds.json:

{
  "betrayal": {
    "sounds": [
      {
        "name": "bomod:sounds/betrayal",
        "stream": true
      }
    ]
  }
}

And i have the betrayal.ogg in the sounds file
