Monsta X is really good! I fell in love with their personalities instantly. They really remind me of BTS. They were formed from the survival show "No.Mercy". Check it out when you have time!
Red Velvet has been the new hot rookie girl group, but I don't really think they're the best. Their songs are catchy. I prefer The Ark, they're so lovable. CLC (Crystal Clear)'s song "Pepe" makes me happy. But don't forget that these "youngins" still listen to all the older groups! I'm 14, and started listening to kpop at 7 because my older sisters were really into Korean dramas and K-pop. (ss501, Big Bang, 2ne1, Super Junior, and SHINee were my favorite groups. I've been with EXO since "What is Love" and recently at the beginning of 2015, I've fallen in love with Bangtan Boys.) Lots of the older groups have comebacks, so be sure to support them and listen to their music! <33 xoxo

There are many of them. Especially girl groups. Lovelyz, G-friend, The Ark (you should check their exo covers), Mamamoo, Sonamoo, CLC, Red Velvet.Velvet etc. But my favorite is Mamamoo because they aare the first girl group of Loen Ent. And all four of them are amazing vocals. They are not just showing their visuals without any voice like other girl groups. You can check them all. But they are not good as old ones I should say. :)

I loveeee Red Velvet and Girls Day :3
