The scale is the real story here: fifty million tracks means AI slop on streaming had become an industrial supply chain, not a nuisance. This marks a turning point — platforms are shifting from passive tolerance to active curation, largely because royalty pools and listener trust are directly at stake. The open question is precision: at this volume, false positives against legitimate human artists are inevitable, and Spotify's appeals process will matter as much as its filters. Expect other platforms to face the same reckoning soon, since the flood is generated upstream of any single catalog.
