This is the second bit of positive news for Vybz Kartel in recent times. The deejay, who is currently incarcerated, recently charted at number 37 on the R&B Billboard Chart with Fever.
Vybz Kartel's 'best-friend' Amelia 'Milk' Sewell for comment on the deejay's current wave of success internationally. The media personality, who also played the substitute teacher on Vybz Kartel's reality show, Techa's Pet, said the deejay is still a trendsetter.
"The copyright money you get from samples is your insurance for further down the line. He has kids to feed, and to see that his music is still being well received, despite his absence, really shows that he is the greatest of all time, like Usain Bolt. He is still relevant, and artistes are still trying to be like him. They don't know what to sing unless Vybz Kartel sings it first," she said.
Milk, who has visited the deejay several times since his incarceration, believes the string of success for the deejay will lift his spirit behind bars.
"This will keep him happy to see that the thing is still up. We are still close and we are still best of friends
