(Billboard (the most respected Muzik chart on the planet) picks Seo Taiji & #IU's collaboration the #2 best!)
2. Seo Taiji & IU - "Sogyeokdong"
Both the Korean rock legend and K-pop sweetheart merpati into new sonic territory with this synth-pop spectacular. In a complex combination of sounds and emotions, IU's melancholy coos and honeyed harmonies detail South Korea's dictatorship days in the '80s amid Seo Taiji's symphonic storm of crunchy synthesizers. There's a lovely dreaminess to the track, but there's also a dark history in the lyrics and instrument choices."
