If My Beautiful Dark Twisted Fantasy is Kanye's Kid A, then "Runaway" is his "Idioteque." The hugely ambitious album was a steep departure from his previous work, and its genius only revealed itself slowly. There's way too much there to take in after one or two listens. The nine-minute "Runaway" is the longest track on the album, and the most whacked-out. It's the sound of him absorbing all the hate coming in his direction, and feeding off it. If everyone agreed with Obama's assessment of him, then Kanye will offer a toast to the douchebags, scumbags, assholes and jerk-offs.
The song is constructed around a single, haunting piano note. At the end, his vocals are scrambled beyond recognition. It's Kanye's way of conveying that nobody is able to understand him or even hear his words properly. The song seems aggressively un-commercial, but it actually hit number 12 on the Billboard Hot 100. If nothing else, it proves that the public will embrace something more complex than a short pop song if they're exposed to it enough.
No matter what Kanye comes up with over the next few decades, "Runaway" will almost certainly stand up as one of his greatest works.
