Taylor Swift debuted her 1980s-style sugary pop hit Sweeter Than Fiction. Justin Bieber dropped Hold Tight for the third installment of his Music Mondays series. Kanye West suffered a major wardrobe malfunction as the crotch of his leather pants split open during the opening show for his Yeezus tour.
