CF (Commercial Film) releases from kpop acts are often pretty flimsy, which makes sense because their whole purpose is to act as an advertisement for whatever product or brand a group is endorsing. Similarly, CF music videos are little more than extended commercials, usually with the product awkwardly shoehorned in. But, Mamamoo’s Woo Hoo is an exception. It’s a terrific song in its own right.

As soon as Woo Hoo kicks off with its lush suite of summertime harmonies, I was brought back to the best of 90’s Mariah Carey style pop. What follows is an effortlessly breezy slice of nostalgia. It feels lighter on its feet than much of Mamamoo’s recent material, and is all the stronger for it. The lively jabs of synth and keys drive this easygoing, bubbly vibe, and brilliantly complement the girls’ always-impressive harmonies. I was initially taken aback by Moonbyul’s rap section, which hijacks the second verse and completely alters the song’s flow for a few moments, but repeated listens have lessened its jarring effect and I can appreciated the dynamism it gives the track.

Though it’s not as much of a statement piece, I think I slightly prefer this over You’re The Best. It feels less thought out, coasting on feel rather than forcing itself to deliver big performance moments. In this way, it’s a different kind of showcase for the group’s considerable talent. I hope the girls decide to give it a stronger promotional push than most CFs get. Its quality certainly demands it.
