Hello! I haven't been posting a whole lot so... Today, I'm going to be giving you some good groups to feast your eyes on.

EXO
The first one is EXO-K/M or just EXO. They are divided into two groups, "EXO-K" is in the Korean market and "EXO-M" is in the Chinese Market. As you can tell, the "M" in "EXO-M" means Mandarin which is the language that they sing.
EXO has released one album so far and (I think) 23 teasers and MVs of What is Love, HISTORY, and their debut song, MAMA.
They have been debuted since April 2012 so if you haven't heard of them, shame on you! EXO is by far my favourite rookie group of all time. There's seriously no one you can hate from there. Don't get too involved with EXO, they'll ruin your life (like they did to me).

B.A.P.
Another group is B.A.P. I call them BAP though. Who cares? Hahaha~ B.A.P. is a group of pretty young teenagers that mostly rap but have at least 20% vocals in their songs. So far, they debuted with POWER as they're first song and then WARRIOR and the newest one (as if now) is NO MERCY. I actually disliked B.A.P. until I heard NO MERCY. But all in all, they're an adorable group even if they are oh-so-cool in their MV's. I actually don't stalk B.A.P. so I only know the basics.

100%
100% hasn't even debuted so I haven't nothing to say. But! Look forward to them! They were in a show with Teen Top since but groups are from the same company. Look forward to the newbies!
