I am a huge fan of 2ne1. I think it was 2012 that they won best new artist in the MTV world awards.
They have 4 talented members Dara, Minzy, CL and Bom. Bom and CL are fluent in English and have lived in the states. Bom went to a music school in Boston. Her parents had actually sent her to school to become a doctor but she went against their wishes and secretly dropped out and went to music school to persue singing.
CL also speaks Japanese, like me and lived in Japan for awhile. She also speaks french and has lived in Paris. Minzy is a really good dancer and grew up competing in dance competitions all over Korea. Dara grew up in the Phillipines and went on an idol talent competition similar to "American idol" and came in second.
So, all of them are really talented and can sing and dance well. They work for YG entertainment and have become world famous. Having done world tours and sold millions of records. The song that won best new artist is called "I am the Best" That's the one I've put here.
Other songs that i love fro them are called "Go Away" which you gotta check out and "Ugly" which is in English.
All of them are done in true KPOP fashion.
