Don’t worry if you haven’t touched a Kingdom Hearts game since the first one dropped back in ‘02—or ever. Though J Mars’ latest single shares a title with the popular series, the record’s less about whacking famous Disney characters on the head with giant keys than about Mars’ own heartfelt desire to become king of the rap game. Corn-Mill Productions cooks up a synth-driven beat that drips with steely determination to back the rhymesayer as he emphasizes his undying drive to succeed. Chill Moody, an emcee previously featured on Lyriciss’ Calling for You, contributes guest bars. For Kingdom Hearts and much more, check out sophomore street release After Lights when it drops digitally in December.
