How do you know Japanese music???

That's the question.

In my case I know it because I heard Anime OP's and ED's and I starte d to like it that kind of music.

The first one J-Pop artist I know was Aikawa Nanase. I know it from a CD which came on an anime magazine. The first songs I heard from her was "Nostalgia" and "Koigokoro". It's one of the best.

yep, this is the same reason for me, i listened OP's and ED's, i don't remenber the first japanese song i heard! but i heard so much, i can't remenber each song of each singer, then also with magazines, i found new singers like Morning Musume and so on, first i have been interested cuz they r cute, but after found their songs i liked them anyway, i'm a big fan of Japanese music

Hey)))
Well,first there were osts,then someone gave me a CD with X-Japan singles and the there was my favorite Malice Mizer. JRock. Yep, it "conquered" my heart. JPop "came" much later. My favorite JPop artist is Korean BoA. As for J-Rock...Malice Mizer.especially with Gakuto-sama.
My ex-boyfriend used to send me lots of CDs,now I download music just from the web. Or take the CD from my friends who go to Japan.As for me,I gonna move to Japan after graduating from the university. Yep,that's it. It'll be a tough job =___=
