hmmm!!! i think thats why most of their songs translated into japanese ver. so that the japanese people who also idolized snsd can really understand and so that if they will have a संगीत कार्यक्रम in जापान they can sing their songs द्वारा translating it into japanese version.... ahm, i think thats all... ::)))
It's because they are promoting in जापान as well as Korea now. When आप promote संगीत in another country, it's only logical to be गाना it in that country's language. And, they probably redid Gee and Genie because they were so popular.
