VTuber NewsDrop confirmed that hololive and NIJISANJI talents appear, alongside Kizuna Ai, HIMEHINA, and indie VTubers like Ironmouse, Isaa Corva, and Bao The Whale. Producers such as Alohaii, PrettyPatterns, and TeddyLoid also have tracks in the datasets. HIMEHINA, Nanahira, Mori Calliope, AmaLee, AZKi, KAF, Derivakat, Hoshimachi Suisei, and Akuma Nihmune each have over 100 tagged results, meaning most of their song catalogues are vulnerable to AI synthesis. LAION-DISCO-12M was built by German non-profit LAION, which received funding from Hugging Face and Stability AI\u0026#39;s co-founder. Sleeping-DISCO-9M was assembled by the Sleeping AI collective.
