It takes a particular sort of darkish, twisted genius to boost the white flag of give up whereas elevating a center finger. Kanye West is that genius. “Runaway” is Kanye’s musical response to the Taylor Swift affair, nevertheless it’s way more than that: a nine-minute meditation on romantic failure and public infamy. Kanye creates an enormous, eerie beat out of thunderous drums and plinking piano, and he turns the phrase “Let’s have a toast for the douchebags” right into a chorus almost as catchy as “She loves you — yeah, yeah, yeah.” In 2010, no different tune was so crazily epic or jaw-droppingly beautiful — not on the radio, not anyplace. Now, everybody elevate your glasses.
