Some disbanded KPOP group who is a living legacy that you should know

It's a fierce battle and every single group out there has their "expiring date", I mean, most of the members themselves try to pursue another career outside their respective groups after their original contract with the agency expired. (Which is by the way quiet long, about 5-7 years). Yet, for a group that hasn't successfully achieve the trophy of winner, a.k.a win any chart for 2 consecutive years after they debuted, most of them will disbanded eventually before the contract expired. It's unfortunate, but with how strict the industry is under the over saturated market, it bounds to happen.

It has been the 4th generation of Kpop already, and thus before we're approaching into a new generation, let's check out some BOP from the pass generation who has been disbanded. It's a shame you don't know them, because all of them is such amazing group, and they are:

1. 2NE1

4 membered girl group is the girl crush model from YG entertainment. Consist of CL, Minzy, Bom and Sandara, steal all international fans by their catchy and easy to listen music. Most of their song is a BOP and you should listen to all their title tracks. Try to listen on their hit track: I don't care, lonely and I am the best,

They are a girl group who break the stereotype that a Kpop girl group should be cute, a next door girl kind of type and have the same beauty standard. All the 4 members are beautiful as they are, individually unique and show cast their own appeal.

2. 2PM

Considering as a "Beast" version of the kpop boy group from JYP entertainment. All the members are so tall, handsome and have muscular body. They aren't some pretty boy next door. Try to watch their MV Heart beat, 10 out of 10 and Come back when you hear this song. Interesting fact is that 2PM used to be JYP money maker and beat twice in term of profits. Their original leader, Jae beom left the group because of derogatory remark that he post on his own private social media, insulting south Korea as a gay country. (It isn't necessary but doesn't mean to be found in public)
