this is so daebak!
seriously it's not actually been heard of in other countries as well i mean just here in the philippines many of the artists who debut in other countries either have english songs and/or translated songs fit to whee they debuted and not a single song is in their mother tongue, this is why i love KARA they never loose sight of where they came from and always remain true to their image and identity.
KARA JJANG! Go Conquer the Japanese Music industry, then come to the Philippines hehe
