I love Japanese songs but I've only listened to a few boybands. ARASHI FOR THE WIN!!!!!!!! I luv them, they're good dancers aaaand they can sing really good. Even on stage..... LIVE! I also listen to Kat-tun, Nobody Knows, Suemith & the Suemitsu, etc. I love both JPOP and JROCK, so if you could recommend me other bands that I should listen to, please drop me a line ^^
Other than boybands, I'm just addicted to Ikimono Gakari, Hitomi Takahashi and Inoue Joe
