omg, how could you, like record the songs?

For me, i'm not a good singer though T.T. I think you should practice your hangul and pronounciation ^^, you should also try dancing while singing. Try controlling your voice when singing, and use your diaphragm, cause i think you are using your throat. Also trying breathing the proper way, cause i could see hear your breathing when singing. You guys/you have a nice voice ^^ don't waste that talent!. When you did the bichi bichi part it was so~ funny!. In 0:39, the girl who sang it should make her voice loud, she has a soft voice I guess. The one who is singing the 'oh yeah' or the background voice, should not be near the recorder so it will be like a real echo LOL. Sorry T.T, i'm not good in judging OTL.
