The use of Tupac’s vocals has sparked outrage from the rapper’s estate, which claims that it never authorized Drake’s use of his likeness or voice. In a cease-and-desist letter sent to Drake’s legal team, the estate’s attorney, Howard King, stated that the track is a “flagrant violation of Tupac’s publicity and the estate’s legal rights.” King also criticized Drake for using Tupac’s vocals to diss Kendrick Lamar, who is a close friend of the estate and has always shown respect for Tupac’s legacy. The issue between Drake and Lamar began earlier this year when Drake released the single ‘First Person Shooter,’ in which he compared himself to Michael Jackson. Lamar responded by taking jabs at Drake on his track ‘Like That,’ likening himself to Prince, Jackson’s longtime rival. Drake then seemingly replied on his diss track, ‘Push Ups (Drop And Give Me 50),’ which features lyrics that reference Lamar’s fifth studio album, ‘Mr Morale & The Big Steppers.’ Lamar has yet to release a rebuttal to ‘Push Ups,’ but Rick Ross recently dropped a song titled ‘Champagne Moments,’ which is widely seen as a response to Drake’s diss track. The back-and-forth between Drake and Lamar has captured the attention of hip-hop fans worldwide, and it remains to be seen how the feud will play out in the coming weeks and months.
