A bad copyright infringement claim
There is a YouTube channel called Vocal Synthesis. It features videos with audio deepfakes (AI generated voices).
The channel received a DMCA copyright takedown notice from Roc Nation LLC for two videos featuring Jay-Z reciting "To Be or Not To Be" from Hamlet and "We Didn't Start the Fire" from Billy Joel. Pursuant to the DMCA copyright claim, the videos were taken down by YouTube. However, they were later reinstated because the DMCA copyright claim notices were defective.
The basis of the copyright claims was that "This content unlawfully uses an AI to impersonate our client’s voice" (see link).
Copyright protects original works of authorship. The author of these videos probably is the owner of the channel. The author of the videos is not Jay-Z. Because Jay-Z isn't the author of the videos, any DMCA copyright claim would not be legitimate. I look forward to seeing if Roc Nation resubmits this DMCA copyright claim.
