As a lover of Kpop, I feel like I have to give some suggestions. I can't think of any that sound super similar, but I will just suggest some of my favorite songs from my favorite groups. For each group I will try to suggest at least one song from each of their themes.
- Pentagon- Like This, Naughty Boy, Can You Feel It, Shine, Beautiful, (half of the group did a cover of Justin Bieber's Sorry. It is pretty epic in my opinion.)
- BlackPink- As if it's Your Last, Ddu Du Ddu Du
- Monsta X- Spotlight, Stuck, Hero, Jealosy
- Twice- Yes or Yes, Likey, Dance the Night Away (Twice is super cutesy and girly. Some people don't like it.)
- Stray Kids- Voices, My Pace, Hellevator (Watch out, the group is loaded with rap talent.)
- BTS- Fire, Dope, Mic Drop, Spring Day, I'm fine
- 4 Minute- Hate, Crazy (Unfortunately, the group has disbanded. That doesn't change how good the songs are though.)
- Big Bang- Loser, Bang Bang Bang, F**k It(I think that is a bad translation.), Let's Not Fall in Love, Sober
- Seventeen- Very Nice, Thanks, Don't Wanna Cry
I think that is plenty to start off with. I hope you enjoy it!
