Music from Corea and Japan

I like listen music from Corea and Japan. Normally the songs are talking about love (I say normally for no say always! XD) and I like this so much because I had listen songs about all and a lot of them don't have sense (from other parts of the world like france, EUA or Spain)

The groups that I listen from Corea are groups of corean pop that is similar to occidental pop but is not the same, they sing in Japanese too!; from Japan I like listen groups of pop, but I like more groups of rock and normally I only listen the songs that I like.

If I like a group it does not mean that I like all their songs. I can't choose only one song like my favorite song because there are a lot of songs that I like so much.

In the future I want to go to one concert of them; some of singers and groups from Japan come here for make concerts but if I go I have to go alone and I do not want to do it, and, always, they make their concerts in Barcelona and I can not go.

Exemples of thegroups or artists that I like:
 

From Japan I listen: X-japan, Gackt, Girugamesh, The gazette, News, Arashi, KAT-TUN, Utada Hikaru, Ai Otsuaka...


From Corea: DBSK, Girls generation, Kara, Super Junior, Shinee, G-Dragon (belongs to the group Big Bang), CNBlue, FT Island, Younha...
