Music publishers sue Anthropic for $3B over ‘flagrant piracy’ of 20,000 works

Three billion dollars. That escalated fast — from 500 works to 20,000. The lawsuit's basically saying 'you trained your model on our music without permission,' which is… yeah, probably fair. The question now is whether Anthropic can survive this or if they'll settle quietly.

This isn't new (labels have sued everyone), but the scale is getting ugly. Fair use arguments work for ML research, but commercial use gets murky. Anthropic's probably got decent lawyers, but $3B is real pressure.
