Some people sleep on Bad. These people are stupid. MJ evolved fiercely on this 1987 blockbuster, mixing the clean disco-pop of Thriller and Off the Wall with a harder, darker electro-rock sound and a new, bad-ass attitude. Classics like “The Way You Make Me Feel,” “Smooth Criminal,” “Man in the Mirror” and “Smooth Criminal” were the result. It’s the fifth best-selling album of all time for a reason.
