• Ziggy Marley takes on racism in this song from the angle that it's an infectious disease that can spread if left unchecked. The cure: humanization and equality. And the best means of transmission: music.
  
  "We are seeing things that were normally hidden," he said on the Off The Record podcast in 2026. "I think that's a good thing because what was in the dark must come to light. Everything happened gradually throughout time, so even though some of the things we've seen are bad, it's in the light now."
  
  "It takes a cycle, but the music is always relevant," he added. "There's always a need for inspiration. We want things to be better and more balanced, but it will never be perfect. We've got to keep trying, moving forward. So yeah, I feel like there's progress. It's funny - it might not be the progress that we think it is, but it is because it's in the light. It's good to be in light."
• Marley released "Racism Is A Killa" as a single from his Brightside album even though he knew it would be a tough song to promote because of the subject matter. When he made the rounds promoting the album on TV, some of the shows asked him not to perform the song to stay clear of any controversy.
• Ziggy produced the Brightside album with younger brother Stephen; years earlier they were in the group Ziggy Marley & the Melody Makers together. It was made at a non-standard tuning frequency of 432Hz (as opposed to the standard 440Hz). Why? "I wanted something different than what everybody else is doing," Ziggy told Off The Record. "That's a big driving force for me. I don't want to fit in a box. I don't want to be a part of the crowd."
• In the music video, Ziggy Marley plays a doctor tasked with treating an acute case of "Racismosis," which is spreading. He successfully cures it through music.
  
  The video ends with a public service announcement about the condition, which lists the symptoms. They include:
  
  Blaming entire groups
  Selective outrage
  Historical amnesia
  Aggression toward others
