SHINee, "Sherlock" (2012)

"Sherlock" isn't an entirely original song, but instead the combination of two separate tracks by Korean quintet SHINee. Mashing up two cuts off the band's 2012 Sherlock EP — the bouncy hip-hopper "Clue" and the impressive vocal track "Note" — "Sherlock" was touted as Korea's first "hybrid remix" single. As an already beloved, already chart-topping boy band under Korea's biggest music label, SM Entertainment, the Jackson 5-recalling tune shows how innovative and experimental K-pop can get, even for its most mainstream acts.
