When news of the 20-year-old's death broke late on Monday night, Spotify added two of his tracks, "SAD!" and "Moonlight", to the top of the popular Rap Caviar playlist.
A note reading "Rest In Peace, XXXTENTACION" was also added at the top of Rap Caviar, which has more than 9-million subscribers:
Numerous Twitter users pointed out that a brand new "This Is XXXTentacion" playlist was soon being promoted on the Spotify Homepage and Browse section too, prompting accusations of hypocrisy and exploitative behaviour:
The rapper's past included a stint in jail, and he previously spoke about "stomping" on his gay cellmate's face and "trying to strangle him", after allegedly catching him staring at him.
Citing this and the domestic violence allegations, other fans have criticised Spotify's decision to repromote XXXTentacion for entirely different reasons:
HuffPost has contacted a Spotify representative for comment.
XXXTentacion, real name Jahseh Dwayne Onfroy, was shot dead in South Florida on Monday afternoon.
He was shopping for motorcycles and was leaving the RIVA Motorsports showroom at around 4pm when he was approached by two armed individuals, TMZ reported. One of them fired at him before they made off in an SUV.
The Broward Sheriff's Office later tweeted confirming his death, after previously stating they were responding to a shooting incident in Deerfield Beach, about 55km north of Miami.
They have since said they believe the incident was a possible robbery and are appealing for information.
Kanye West is among the celebrities who have paid tribute to the rapper, posting on Twitter: "Rest in peace. I never told you how much you inspired me when you were here. Thank you for existing."
