Has this happened to you? Or anyone you know? Or do you know of a lawsuit by a label against an artist for making AI music, and a lawsuit by the same artist against an AI detector for flagging a false positive. This story seems extremely unplausible.

Aside, your analogy doesn’t make sense. Horoscopes are generally not in the business of signal detection, and are usually enjoyed by the reader of the horoscope, like any other art. If you had used a sudoku solver your analogy would make a bit more sense.
