I used the generator to create a new music disc. The disc is successfully pulled from the inventory but does not appear inside the jukebox and plays no audio.

Sorry y'all this is really late but I fixed it 😭 It wasn't an issue with the mod, but with the generator.

Does not work for me either :( The same symptoms, the added disc items exists and everything, and upon interaction with jukebox, item is consumed (won't be consumed in creative mode, as expected), but nothing happens beyond - no text or music, and cannot retrieve the disc (treated as if nothing is inside the jukebox) Tested it with a minimized version of my instance to test and does not work either, the mod list goes as follows: -quilt loader 0.23.1 -quilted fabric API (qfapi-7.5.0_qsl-6.1.2_fapi-0.91.0_mc-1.20.1) ---also tested with fabric-api-0.89.0+1.20.1 -disco-2.0.8 -addon pack created with the website including 1 disc I haven't tested with fabric loader however Included is this mentioned test addon pack just in case: lalala-test-1.zip

Was the music file added in .ogg format?

In my case it was in the .ogg format.

yep, it is .ogg, single mono channel as advised in the page

:O thank you! been a while but don't worry

1.20.1 btw
