38. B1A4 - "Road" (Who Am I, 2014)
A laidback, reflective pop-rock track about past promises made amid hardships, "Road" balances warm vocals with a dominant synth beat and piano melody. It’s effusive yet mellow, and unlike many K-pop ballads that struggle to find a place for the group’s rappers, it cleanly incorporates several soft-toned rap verses from Baro over a clapping rhythm. Like much of B1A4's discography in recent years, it was written by the members and plays up each man’s artistic strengths to craft an elegant, midtempo tune. -- TAMAR HERMAN
37. CNBLUE - "Like a Child" (Can't Stop, 2014)
While CNBLUE's 2014 single "Can't Stop" highlighted the band's ability to craft accessible, feel-good rock-pop, the EP also had an undeniably strong standout track in "Like a Child," which was equally accessible and included an uplifting mood and melody that recalls some of the best Coldplay songs. -- JEFF BENJAMIN
36. Teen Top - "I Wanna Love" (No. 1, 2013)
Teen Top's first full-length album No. 1 signaled a sonic shift, kicked off by the buzz track "I Wanna Love." While you could still play it in the clubs, like past singles from the outfit, the cut stands out for its melancholy vibe and layered harmonies. The lyrics of the track also seem to indicate the Teen Top boys were ready to embrace change, singing, "It's time to move on, here we go, Teen Top." -- J.B.
35. Sistar - “Good Time” (Shake It, 2015)
Who else but the Queens of Summer could make you want to party after a breakup? “Good Time” has the kind of earworm chorus where main vocal Hyolyn easily weaves between belted notes and sweet falsetto embellishments. Glitchy saxophone colors the catchy banger. The lyrics are almost too dismissive of a former lover to count as a kiss-off. The girls are too busy having fun to care about any love lost. Although the quartet disbanded in June 2017, their impact on K-pop will last longer than the summer heat. -- C.K.
