Their full name is K/DA & Madison Beer and they have two other artists name. They are good band. My favorite songs made by them are Popstars, Baddest, More, Villain, and Drum go Dum. I don't really like the other two songs I didn't mention. You guys should check them out. And keep in mind I am under 18, so my opinions are going to be far from similar for most of the time. But still you guys should check them out!
