In Wednesday's letter, however, the estate said that California's existing publicity right laws clearly outlaw something as blatant as Drake's use of Tupac's voice in "Taylor Made." King argued that the song had caused "substantial economic and reputational harm" by creating the "false impression that the estate and Tupac promote or endorse the lyrics for the sound-alike."
The estate also argued that the song was likely created using an AI model that violated the estate's copyrights by "training" on existing recordings of Tupac's music. The legality of using copyrighted "inputs" is another difficult legal issue that's currently being tested in several closely-watched lawsuits against AI developers, including
one filed by major music publishers.
"It is hard to believe that [Tupac's record label]'s intellectual property was not scraped to create the fake Tupac AI on the Record," King wrote, before demanding that Drake also provide "a detailed explanation for how the sound-alike was created and the persons or company that created it, including all recordings and other data 'scraped' or used."
Wednesday's letter also pointedly highlighted that Drake himself has made previous objections to the use of his own likeness by others. In addition to last year's incident surrounding "Heart on My Sleeve" — which was quickly pulled down from the internet — King pointed to a lesser-known federal lawsuit in which Drake's attorneys accused a website of using his image without authorization.
"The ["Taylor Made Freestyle"] has generated well more than one million streams at this point and has been widely reported in the general national press and popular entertainment websites and publications," the estate wrote. "Without question, it is exponentially more serious and damaging than a picture of you with some other people on a low volume website."
