There’s probably loads of examples I could name but I’ll name the one sticking out in my head the most.
Basically. The easiest way to describe it would just be “SHOOT! - BY ITZY” in capitals because oh my god.
The most obvious detail I love would be in the second chorus, where I believe either Ryujin or Chaeryeong is singing, where the instrumental changes very briefly in like a ringing sort of way. I love that part so much. It’s such a small thing but it sounds SO GOOD.
But like Shoot is so much better when you listen to it with headphones. THERES SO MANY HIDDEN VOCALS and if you listen closely you can pick them all out. Mostly sort of just talking and murmuring but they contribute so much to the song. One example I can give which is easy to notice is the outro with the “la la” part sung by Chaeryeong. While not immediately noticeable, during that part there’s like echoy las sang alongside it. It’s heavenly
Anyways that was my essay about why Shoot! is like my favourite ITZY song yep im declaring it right now
Edit: most of them are sung by Yuna as well LIKE HER IMPACT
Edit 2: omg I completely forgot to mention the chorus, where the members sing in age order, and then back again in reverse order
