...they actually tried to appeal to Western fans? I feel like their heart is still in Korea. They're a pretty well-known group over there but they're not necessarily the most popular.
I noticed they don't really try to appeal to international fans, maybe a little in Japan releasing Japanese versions of their songs but it seems that their main focus is in Korea. They're one of the 3rd gen groups that aren't really catering far beyond their borders.
I think that if they promoted themselves a little more to the Western market, Japanese market and other countries, they could make it pretty big. Or maybe do you think that it's their concepts/music that's setting them back?
