Pun alert — a bilingual one. The fourth track, "Gray So Gray" featuring Younha, is a song about the love, hate, and frustration between a couple. The song's original Korean name "그래서 그래 (geu-rae-seo-geu-rae)," which translates to "that's why," sounds exactly like "Gray So Gray." The Korean title describes the situation where the lovers are trying to explain things to each other, and the English title captures the mood of the song on point. Great, so great.
