Perhaps there won't be any female solos in the top ten this year? Last year only one made it; Mika Nakashima, at number 10.
for 2004 there were only three, COUNTING GORIE.

I guess the trend is going against female solos and it's continuing this year.
Let's just hope that Ayu can make it to the top 10 this year with her new mega-summer release! Last time she was in the top ten was when "&" was released....
