i used to don't like Ayu very much, i heard Ayumi and Utada was big and i listened to both their music and im like "omg that Ayumi girl songs suck, Utada is better" Utada wasn't my fav artist though, i just thought she was better -_-"
2 years later....
i went to a forum and the thread was "Your fav Jpop Song?"
so many people said Ayu so i started downloading some of Ayu's songs and got sooo HOOKED! and i listened to the songs i used to hate and now i love

i always think back "how could i not like this song? i'm the stupidest person in the world for missing out on such good music for 2 whole years"
i should have been a fan since 2002 but it only started in 2004, my bad
