I liked 2ne1, BP is also good. Although I didn't like how YG treated 2en1, where they found out the disbandment through media. Maybe YG was trying to get rid of in-house GG competition and so they throw away 2en1 and debuted BP. Or to prevent the same producer and sounds, they could only have 1 GG at a time, since Teddy is producing everything.
Baemon is very new and so no opinion. Although I did see some predebut clips of their members having vocalist abilities, that's all I know lol. Do not know their names though.
