@cooksta82 Check out P-Pop (Filipino Pop) LOL. I'm not suggesting it because I'm Filipino, but because plenty of those groups sing in English anyway. Check out XLR8, 1:43 (though I don't think they have any English songs, but they're such an awesome group), DTM/Down To Mars (they really look like a K-Pop Group because most of them are half-Korean, half-Japanese, half-Chinese), hm what else... LOL. They're all over YouTube.
As far as J-Pop goes, I really don't know much about their newer stuff. I really love their older stuff (late 90s-2000s). And of course, you can't forget the songs you hear in various anime, that's a plus.
As far as K-Pop goes, so far CN Blue, FT Island, some 2NE1, and some SNSD are the ones I listen to the most. I regularly tweet with Dara of 2NE1 because we both speak the same language (Tagalog/Filipino LOL). Well she speaks English too, but mostly Filipino (aside from her native Korean).
I like Kyary Pamyu Pamyu also. I follow her Twitter and she has her international Facebook fanpage that she and her management maintains (all in English too). Scandal is pretty good too. But I know mostly male groups/artists, so ^^;
