fromis_9: "love bomb". their best single to date, best music video, and it should have been their breakout hit. it will forever be one of the best k-pop songs of all time. it was a turning point for them, though, and brought in many new fans, so it wasn't entirely underappreciated, thankfully.
lovelyz: all of their eras are fantastic, but "destiny" was another level. it was so ethereal, elegant, and we even got blonde jiae and yein
"obliviate" is a close second, however.
nature: i never expected them to go so dark and mature with "girls", and it was a pleasant surprise and garnered them more attention. i hope they continue on with this concept and sound, as it fits them like a glove.
oh my girl: "closer" will never, ever, ever be topped. it was perfect in every way. the constellation-inspired choreography is such a cool idea.
red velvet: "ice cream cake", because not only was the album, styling, hair, and choreo perfect, but we also got precious yerim
wjsn: "secret" was the perfect intro for yeonjung. it's such a magical song and i don't think they've come close to how perfect everything was.
