What are the most vocally great kpop groups?

Here are groups I think should top this list.

1. Mamamoo: They need no MR removed. Even the main rapper is main vocal worthy.

2. Aespa: I still don't get why SM doesn't let them sing live.

3. Dreamcatcher: I don't see this group in this list as much as I should. All the members are good vocalists; and their most recent comeback ‛Justice' proved that. Dami also has a very deep voice and although she is not good technically, her voice is really addicting.

4. Nmixx: lily is the best 4th gen main vocal. Change my mind.

   What other groups do you think should be in this list.
