Tupac Shakur’s estate has threatened to sue Canadian rapper Drake and ordered him to delete a track featuring an AI-generated copy of the late rapper’s voice on a diss track.

Shared Friday on Drake’s Instagram account, the track, “Taylor Made Freestyle,” was aimed at rapper Kendrick Lamar, whom Drake has been entwined in public rap beef with lately. It also included what appeared to be an AI-generated voice from rapper Snoop Dogg, as well as verses from Drake himself.

In the song, a fake Shakur can be heard taunting Lamar, rapping, “You asked for the smoke, now it seem you too busy for the smoke.”

A cease-and-desist letter issued by Howard King, an attorney who represents Shakur’s estate, requested that Drake remove the track from all platforms where it is publicly available. Drake has until midday on Thursday to confirm he will remove it or the estate will “pursue all of its legal remedies” against him.

“Not only is the record a flagrant violation of Tupac’s publicity and the estate’s legal rights, it is also a blatant abuse of the legacy of one of the greatest hip-hop artists of all time,” Mr King wrote.

“The estate would never have given its approval for this use.”

The letter also outlines the estate’s “dismay” regarding the topic of the track, saying Lamar is “a good friend to the estate who has given nothing but respect to Tupac and his legacy publicly and privately” and that this “compounds the insult”.

The letter claims the track and its popularity have created the “false impression that the estate and Tupac promote or endorse the lyrics for the sound-alike”.

Shakur’s estate is also seeking damages including all profits from the record, which has so far only been posted on Drake’s Instagram page, as well as additional damages for substantial economic and reputational harm caused.
