Hmm... Twice, Itzy, Stray Kids, and lots of kpop groups have lots of good content (music, challenges, reality shows, etc.)
There's also a few channels I use to help learn languages by watching vlogs and things like that! Like loane (french), 醋醋汁儿 (chinese), 지아잉jiaing (korean), and diana gaby (spanish)!
Other than that I don't watch many other youtubers!
