Maybe they can measure entropy. Did you emit a sufficient amount of data to make the Music Box work, given the Copyright Office defined ratio?
For every unit of data in your song, you must have emitted no less than 1/2 of a unit, which was specifically intended to manipulate the Music Box in order to shape outputs. Any less and the creation isn’t yours.
What do you mean I can’t copyright this song? My air drumming against the cassette player introduced very significant data, which adjusted the playback. Just a very slight legato. It’s too similar? I assure you it is not. Convert the two to Universal Data Format and check the Hamming distance. Incredibly different pieces of data, believe you, me.
This is basically the origin story for how the US Copyright Office became the galaxy’s Entropy Police. “Back in 2023 someone tried to copyright a photo of an “ottercat” surfing a DeLorean on the moon and now we’re in charge of how organized is too organized.”
