Custom music disc audio cuts off early due to original disc length limit (Jukebox)

I have created a resource pack to replace the audio of Minecraft’s music discs with custom songs. However, the custom songs always cut off at the length of the original music disc’s audio.

For example:

• If I replace "11" (originally 1m 13s) with a 3m 17s custom song, it still stops playing at 1m 13s.

• This issue happens with all custom disc replacements.

• I have properly configured the pack and the sounds.json to include the correct length values, but the game does not respect them.

• The issue has existed since around Minecraft 1.19 (2022) when changes were made to how redstone interacts with jukeboxes.

This bug prevents custom music discs from playing at full length, even when configured correctly.

Steps to Reproduce:

1. Replace a disc’s audio using a resource pack.

2. Update sounds.json to set the correct custom length.

3. Play the disc in a jukebox.

4. The song will stop at the original vanilla length instead of playing fully.

Expected Result:

Custom disc audio should play in full according to the length set in sounds.json.

Observed Result:

The music stops early at the vanilla disc length, ignoring sounds.json settings.
