You could create sound ids. For example, in the properties file entity.player.attack.sweep=citresewn.sweep. Like if you had a music disc and you wanted to change the sound, and then you use a sounds.json file to create the soundpath.

Sadly I cannot do music discs because the exact item in the jukeboxes is not synced to clients.

However maybe some item related sound events could be a neat addition.
