Big Bang - Haru Haru. I first heard of them when my friends showed me the video on youtube smile
yeah that was the first song i hear from them too, been my fav ever since, but i also like ZE:A's Harujongil and i heard them both the same day! they both are my favorites! and i hope ZE:A's Heart for 2 comes out in japanese, cuz both haru haru and harujongil are in japanese, and Big bang's Lies comes out in japanese too!
I saw CN Blue's cover of "Geek in the Pink", but that was before I knew about Kpop, and that they were a Kpop group. But the first actual Kpop song I heard and MV that I saw, was Super Junior's
A-cha. 4laugh
