Along with OutKast's "Hey Ya!" this was quite possibly the most ubiquitous song of the decade. Rapper Cee Lo Green, working with hot producer Danger Mouse, was remade into a soul singer, and the resulting sounds of the single are all over the place. Lyrically, this is a paranoid freak-out, but also a bit aggressive. Musically, it's vintage, but with plenty of modern touches. Crazy? No doubt, but even more chaotic. If there was a sound to the decade, this was it.
