Hmm lets see here...
BoA - Used to be a huge fan but i dunno, she just got boring after a while
Koda Kumi - Her older stuff was great, but i just have no interest in her nowadays.
High & Mighty Color - I was a fan for a short time but then realised 90% of their stuff just isn't really that great at the end of the day.
Bonnie Pink - Don't get me wrong here, i AM actually still a fan and consider her to be one of the best artists in the world, but her recent stuff just hasn't interested me at all... i can't see her topping Even So
Namie - I loved the STYLE album, but nothing since then has prompted me to pay any attention.
