Their whole discography, they have a lot of experimental songs and they was never ashamed about their songs (compared to exo and wolf or aespa and supernova).
When i listen to them, I know the genre is kpop, it’s not like SNSD or 2ne1 that sound like kballade, american 00s pop or electro pop. I can’t explain more, I hope yall understand what i want to say.
