I absolutely Within Temptation! It's either the awesome music or the female vocalist... You can choose which you like best!
Anyway, I listen to a ton of Japanese, Chinese, and Korean music. It has its appeal to me. Well, the Japanese are definitely the coolest and then the others pretty much fall in line after that. Gackt, Namie Amuro, and Ayumi Hamasaki are my favorites. I listen to Yuki Hsu, L'Arc~En~Ciel, Moi Dix Mois, Malice Mizer, BoA, Lee Hyung Jun (I think that's how you spell it), and Vanessa-Mae.
Vanessa-Mae is more of a revolutionary artist than anything. She's a Vietnamese violinist who used to do all classical. Now, she does classical with a contemporary techno flare. She also does a lot of singing in English, French, Spanish, and a ton of other languages that she is fluent in. She is definitely one amazing woman! My IDOL!!!
