I don't exactly remember when. But, once upon a time, my friend wanted to mostra me, what she called, this "creepy, Japanese shit". It was a PV called Obscure da the Japanese rock/metal band, Dir en grey. I thought it was awesome and fell in Amore with the band. Then, I started to listen to other Japanese bands after that.
Well... Anime showed Giappone to me ^^ I thought: Wow they look like real people! Actually it was an accident that I saw it lol xD After, I asked my brother from which country Anime comes.. Then I fell in Amore with Giappone and I still Amore it! Then I watched a lot of animes and heard the opening songs. I just loved them. Then I found più songs and I couldn't stop listening to them :) My favourite singer is Yui Yoshioka with her song Goodbye Days.. My dream is to visit Giappone one giorno :) Their snacks are soo good ^^ Giappone rocks ~^.^~
I, too, got to know Jmusic because of anime. I was a bit of a Japanholic before that, but after I got introduced to the Anime and manga world... it was only a matter of time untill I started listening to certain artists (and actually knowing who they are xD) and listening to songs and artist that never appeared in anime.
i was only about 7 my sister showed me a Anime called death note and then i LOVED the theme song so i learned to sing it i got OBSESSED with Anime a bit later i then watched a Anime called Black Butler - Il maggiordomo diabolico o in english black butler i was one of the few who watched the secondo season and i heard the theme song for the secondo season and i fell in Amore with it and i found out what it was and it turned out to be shiver da the gazettE so i watched the Musica video and i fell in Amore with the band and would not stop listening to they're music (kuroshitsuji/black butler)
when I started listening to J-rock o J-pop was when I had my obsession over Anime which was three week's ago. the thing that got me hooked was the sound of the Musica and it was different from American music. I just fell in Amore with it! :)
