Jimmy Mizen, 16, died at the Three Cooks Baker in 2008 when then-19-year-old Jake Farhi threw a large glass dish that shattered and severed an artery in his neck.
Fahri was jailed for life with a minimum term of 14 years for his murder in 2009 but he was released on licence in June 2023.
The Sun reports that Fahri is now a drill rapper named TEN whose songs have been played on the BBC, with glorifying violence.
His lyrics include: “See a man’s soul fly from his eyes and his breath gone. S***, I wanted more, it made it less wrong. Seeing blood spilled same floor he was left on.”
In another song he said: “Stuck it on a man and watched him melt like Ben and Jerry’s. Sharpen up my blade I’ve got to keep those necessary.
“Judge took a look at me, before the trial even started he already knows he’s gonna throw the book at me.”
Jimmy’s mum Margaret told the BBC: “We’re a bit shocked, we’re just taking it in. How can someone be allowed to play this kind of music? The words are absolutely horrendous.
“I think he’s a coward. To be able to play his music with a balaclava on and not show his face says to me he’s a bit of a coward.”
Jimmy’s father, Barry Mizen, told the PA news agency that parole statements said Fahri has “done all the programmes” but that “doesn’t seem to have made a blind bit of difference”.
“I think it does strike quite a few questions about the whole (prison) system – what’s the point, you know?”
Fahri started and finished his sentence as a Category A prisoner, Mr Mizen said, which is the highest security level.
The family had expected he would have gone to lower security facilities before release.
Mr Mizen told PA: “I think there’s some questions there certainly for the parole board.
“We hope they’ve made the right decision, only time will tell, and perhaps they haven’t made the right decision.”

The family have spoken in many prisons over the years and Mr Mizen said: “A lot of people (say) I’ll do that course, I’ll do that course – I’ve all done all these courses, you can now let me out.
“You just wonder, absolutely the courses should carry on, but… how much manipulation is there of that whole thing by people in prison?
“If you’ve done 15 years in prison and nothing has changed – and it appears nothing has changed (in Fahri’s case) – then we’ve got to consider what is the point of this? Is this something that needs to be looked at again?”
Mr Mizen added: “There is definitely remorse from what we’ve seen in some of the people we’ve spoken to (in prisons), but perhaps it just doesn’t apply in Fahri’s case.”
The Ministry of Justice has begun an investigation into Farhi following the allegations.
A spokesperson for HM Prison and Probation Service said: “We are aware of this content and are investigating it as a priority. We take any material that could glorify violence or distress victims extremely seriously.”
It is understood that the two songs by TEN have been played on BBC Radio 1Xtra’s Introducing show were not those that reference the violence.
In statement the BBC said: “Decisions on music are made on a case-by-case basis and we have strict editorial guidelines in place before any content is broadcast or posted.
“BBC 1Xtra does not glamorise violence and this individual does not feature on any playlists.”
Fahri murdered Jimmy following a row at the Three Cooks Bakery in Burnt Ash Hill.
Jimmy celebrated his 16th birthday only the day before, and had just bought his first lottery ticket from a nearby newsagent.
He and his older brother Harry had then gone to the bakery where they queued behind Fahri to buy a sausage roll.
When trying to leave the shop, Fahri barged into 6ft 2ins tall Jimmy who then refused to move out of his way.
Fahri took offence at being asked to say “please” and began hurling abuse at the two brothers while jabbing his car key towards Harry’s face saying “ok – you two outside”.

The Mizen brothers stayed inside the shop while Fahri went outside, goading the pair to join him for a street fight.
But when Fahri saw Harry making a phone call to his older brother Tommy, he ran back into the shop shouting and swearing.
He lashed out at the brothers’ heads with plastic drinks bottles and it was this attack which finally triggered the pair to fight back – charging at Fahri and sending him crashing through a glass cabinet.
The pair were seen by four eyewitnesses giving Fahri a “pummelling” with a barrage of punches to the upper body before bundling him back out of the shop and closing the door.
Fahri then picked up an advertising board and re-entered the bakery by kicking-in the glass door.
He lunged at Jimmy with the sign before picking up a glass dish full of sausages and hurling it at him, killing him.
Fahri, who pleaded not guilty to murder, ran out of the shop and was described by one eyewitness as “walking with a swagger” while another said “he had a big grin on his face”.
Three days after the killing he booked himself into a hotel room under the name Jack Walker where he said goodbye to his girlfriend before turning himself into police.
Since Jimmy’s murder his parents, Margaret and Barry, set up The Mizen Foundation to share his story and to make a difference in the lives of young people.
The couple were awarded MBEs in 2013 for their work.
