A Summer Song, Six Years On — J.Y. Park's 'WET'

In three lines

• J.Y. Park released a new single, 'WET', on July 23. It's his first 'summer song' in six years.
• It's a latin-pop dance track, a strong synth theme laid over a reggaeton beat.
• It also serves as the main theme song for 'WATERBOMB 2026'.

Six years, for a 'summer song'

It's been six years since J.Y. Park last put out a summer song — since 'When We Disco' in 2020. He's had new songs in between, but a track aimed squarely at 'summer' is a first in a while.

The song lays a strong synth theme over a reggaeton beat — latin-pop dance. The more the hook repeats, the more your body reacts before you do. He wrote the lyrics alone and took part in the composition.

Reggaeton isn't a rhythm you hear often in Korean pop yet. It has a particular sticky, springy pulse, and it pairs strangely well with heat. This isn't a summer song that cools you off — it's one that holds the heat and shakes it. It's also where J.Y. Park's long grounding in black music meets a latin rhythm.

A song made to be used on stage

'WET' is the main theme of 'WATERBOMB 2026' — made to sit on top of a festival where you run around getting soaked. The title says as much. It puts the word for getting wet right in the song's name.

J.Y. Park himself takes the WATERBOMB stage on July 26, at KINTEX in Goyang, Gyeonggi. Hear the song first and you'll see how that stage is built more clearly.

There are music-show stages timed to the release, too. Starting with M Countdown on the 23rd, the release day, then Music Bank on the 24th, Show! Music Core on the 25th, and Inkigayo on the 26th. The WATERBOMB stage and the music-show stages fall in the same week, so this week you'll run into 'WET' just about anywhere.

A summer at 54

At the teaser stage, what got people talking was his body before the sound. He revealed a shirtless silhouette, and 'living legend' reactions followed. Someone this far into his career still saying he'll stand in the middle of summer.

Maybe that's the real message of the song. That summer, regardless of age, is just summer.

Discovery note

Play it in the middle of the day, when the sun is hottest. It suits a sweaty spot better than one under the air conditioning. Reggaeton's sticky groove pairs oddly well with the heat. And if you're heading to WATERBOMB, it's worth getting into your body ahead of time.

Just give it a listen, trust me.
