A perfect litmus-test track: To elderly ears, this was an abomination of horror-movie string stabs, discordant samples, machine-gun hi-hats, and frightening voices screaming, "Dipset! Dipset! Dipset!" But to the acclimated Dipset faithful, it was a blissful storm of riot music and Juelz Santana's chest-puffed piffery. It's like one of those weird machines that emit annoying sounds only young people can hear, just in reverse.
