I've had my digital art flagged a few times for various reasons (automatic copyright infringement and NSFW filters) -- so this is nothing new (in particular the artwork blocked the upload for some artist songs). The only thing is to have a reasonable appeal process. In all cases we got an automated approval after appeal, but it can put an untimely delay.

Honestly I hope that the AI filter would be much better in terms of false positive than the aforementioned one, if only because it should be easier via statistical methods.

The only reason you're saying that is because you haven't tried to build such a detector yourself. It's not like text where it's impossible to tell reliably if something's AI generated or not, from a technical perspective it's very trivial to detect anything coming straight out of a Suno/Udio prompt.

Nobody open sourced their detection algorithm as that would just trigger a cat-and-mouse game between Suno/Udio and a detection platform (and Suno/Udio have way more VC money than you do), but plenty are being sold as a service and work very reliably.

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.
