What song should i sing?

Okay. So im korean, and i speak korean fluently and can write korean pretty well and read it well too. And i can also speak and write english VERY WELL because i grew up here... As you can tell... But im gonna try to audition for sm, yg, cube, or jyp or just any entertainment. And i was wondering what song i should sing... And if you dont mind can it be a little modern? Thanks! <3
