76. Major Lazer feat. Bruno Mars, Tyga and Mystic, "Bubble Butt"
As joyfully jiggly and deliriously physical as its subject, Major Lazer's twerk-enticer lures its featured guests into some inspired raunch amidst the bottom-heavy (heh) bass and squiggly synths. If Miley had wriggled to this on national TV, no one would've batted an eye – they would've been too busy turning around, sticking it out, showing the world what they got.
