I've realize this recently, the reason what I like from a band, beside of the music, is also the voice from the vocalist. I love beautiful, strong, powerful, unique, and funny voices. I've also become to like the voices while just talking normally or doing interviews. Here are some voices I like the most for right now.
Hyde sama (vocalist of L'Arc~en~Ciel)
Yasu san (Acid Black Cherry)
Mao kun (vocalist of SID)
Kirito (vocalist of Pierrot and Angelo)
Futoshi san (vocalist of Aqua Timez)
But, I think, for me, there's only one voice I will always love and be waiting to hear. The voice of this great man.
Kimi Raikkonen (vocalist of him self XD)
