we all lie, ost sky castle

Used to be Trouble Maker, but since it's been trending like crazy on TikTok it no longer holds that nostalgic sound anymore... But I'd say something like KARD's Don't Recall, although it's not that old. Hyuna's Ice Cream is also a good mention!

Super Junior's "Sorry Sorry" (2009) 

         

"Haru Haru" by BIGBANG 

Everyone and their mothers beat me to Oneshot - BAP and Loner - CNBLUE , so I'll have to change.

Also known as Enough by Hoppipolla, it makes me so nostalgic for a non existant soulmate that sailed the 7 seas with me.


Someone might have beat me to this one but idc. B1A4's Like A Movie has the instrumentals that trigger nostalgia, especially during the chorus.
