In 1.13 item record requires an integer be passed to its constructor, used as a comparative value. For checking what's already in the jukebox as far as I can tell. How should I handle this?

I would suggest using something in the range 13-15, considering there are the 12 records already using 1-12.

If you look at the usages of ItemRecord#getComparatorValue you can see that it is used for the comparator redstone output strength, not for comparing against the record in the jukebox.

You can put whatever you'd like in it, not that you can have more than 16 redstone strength variants anyway, and I doubt players who use modded need your disk to output a uniqie strength anyway.

Yeah it doesn't seem like I'll be screwing anything up by passing through a zero. Thanks.
