Sunmi releases new music so infrequently that even an under-the-radar duet like Lights Out (불이꺼지고) fills me with excitement. The song pairs her with popular rapper BE’O, whose performance here is halfway between a rap and croon. That fits the vibe of the track, which is smooth and unbothered by any need to deliver more than a stylish groove. Aesthetically, it’s hard to complain about Lights Out. It’s aloof and cool without even lifting a finger.
But other than moody background music, there’s not much to sink your teeth into here. The song relies on an oft-repeated melodic hook and rarely raises above a breathy coo. I could imagine Lights Out making a nice backdrop to a scene in a movie, but I have little use for it on its own.
