Meh, K-Pop is kinda boring to me. I only like BoA, Wonder Girls, Younha, and Cherry Filter. I'm not too big of a fan of K-Pop; I'm kinda the odd one out among my Korean friends because I'm way more into J-Pop than I am into K-Pop.
J-Pop is just a lot more appealing to me.
In addition, I think the Japanese language sounds a lot nicer than the Korean language. I still think the Korean language can sound pretty, but it can also sound pretty rough. I guess that's another reason why I like J-Pop more than K-Pop.
