“Can they unrelease this mess”: BIGHIT’s new boy band CORTIS’ first song ‘GO!’ has fans divided over “heavy autotune” ahead of official debut 

On August 11, 2025, CORTIS, HYBE, and BIGHIT MUSIC’s newest boy band released their pre-debut single GO!. Within an hour, the track set off a talk online. The lineup - Martin, James, Juhoon, Seonghyeon, and Keonho - unveiled the song alongside their first concept photos.

GO! serves as the opening track for their debut mini-album COLOR OUTSIDE THE LINES, set for full release later this month. However, feedback has been split.

"Can they unrelease this mess😭😭," an X user commented.

Some listeners highlighted the track’s energy, while others criticized its heavy autotune. Comparisons have also been drawn to Western rap styles, with some noting it diverges from what they anticipated for a debut.

Just listened to cortis new song, i kinda like it cuz it sounds refreshing oike it was made for summer but it gets annoying when theres a lot of autotune going on so overall its a 6/10

I wanted to give Cortis a chance 😭😭😭 but the first thing I heard was so much autotune the song is so badd byee idk why I expected y2k vibes or new version of shinwha shinee type 2 gen bg 😭😭 I think bg kpop music isn't for me I fear

Meanwhile, others liked the song, saying the autotune was "used mindfully" in it.

Just listened to GO by Cortis & I actually like it​While I do have autotune fatigue in Kpop to a degree, I actually think the autotune in this song was used mindfully, enough so at least that it wasnt grating & was actually enjoyable (imo)​Overall, hype song & good impression
