J. Cole’s KOD has been lauded as one of the best albums of the year, and now it is officially certified platinum, selling one million album equivalent units. This is a huge feat in the music world, as the project has no features.

The album gained praise for addressing topics including addiction, which he saw with his mother growing up. He opened up about how it affected him on “Once an Addict (Interlude),” where he rapped, I used to stay out later on purpose/Subconsciously I was nervous/That if I came home early then what would surface was /Her inner demons/And then I’d have to end up seein’ my hero on ground zero/Tears flow while Al Green blow.”
