It’s been a while since we’ve heard from CNBLUE, so it’s great to see them come back to the KPOP scene. The veteran second-generation band’s last comeback was with A Sleepless Night in 2024, the lead track from their 10th mini-album, X. Earlier this week, the band returned with their third studio album, 3LOGY, and the lead single Killer Joy.

While Killer Joy is no I’m A Loner (for those who don’t know, this is one of CNBLUE’s biggest hits ever), I enjoyed the track for its lively, upbeat pop-rock. This is quite refreshing for CNBLUE as far as I can remember. I like how electrifying the guitar work is in Killer Joy, while the drums help bolster the track. JUNG YONGHWA’s vocals are solid, as always. I also liked the chanted bits of the song, which work well in the pop-rock environment. It was great to also hear the other members, KANG MINHYUK and LEE JUNGSHIN, during the performance of Killer Joy. While the melodies were great, I thought they could have been a bit sharper. But honestly, that is only a minor thing to work on in Killer Joy. I emerged from the song extremely satisfied and have been going back for more of Killer Joy.

In the description box on YouTube, FNC Entertainment has provided this summary of the music video: Beginning in the intimate setting of a rehearsal room, the music video for ‘Killer Joy’ depicts the gradual expansion of CNBLUE’s music, eventually connecting with the audience and transforming into a single, shared stage. Their powerful energy and immersive band performance create an intense sense of liberation. It doesn’t get more straightforward than that. I liked the montage of the members performing their songs and instruments in leather jackets between the first chorus and the second verse. It was brief, but a cool montage.
