Put your “Lighters” up. Eminem and Royce da 5’9” join forces with Bruno Mars on their unexpected collaboration from the Bad Meets Evil EP Hell: The Sequel (June 14). The inspirational anthem, produced by Eminem, The Smeezingtons, and Battle Roy, boasts triumphant verses from Em and Royce (“I remember when T-Pain ain’t want to work with me”), climaxing with an uplifting hook from Bruno (“This one’s for you and me, living out our dreams”). Underdogs unite.
