A track, titled My Favourite Song, locally produced by Stone Cold Records, was recorded in 2011 by Buju Banton, but was released only a month ago.
Mark Hudson, head of Stone Cold Records, said he decided to release the song to maintain a positive image for Buju Banton.
Buju was recently photographed entertaining his fellow inmates at a Georgia correctional facility in the United States and the images went viral on social media.
Buju, whose given name is Mark Myrie, is currently serving a 10-year sentence, and is scheduled to be deported to Jamaica in 2019.
