Oricon does this survey every year to see the most liked artists; 20,000 people were asked who their favorite artists were and Ayu... wasn't there... Do you think she's losing popularity? Come to think of it, when was the last monster hit ayu had? You know, like REALLY REALLY popular? Wasn't it BLUE BIRD? What do you think of this? ...I'm a little sad and shocked.

If anyone is curious, here are the top positions:

1. utada hikaru
2. kobukuro
3. aiko
4. mr. children
5. dreams come true
6. southern all-stars
7. amuro namie (WOAH! didn't expect that one so high...)
8. b'z
9. spitz
10. arashi
11. fukuyama masaharu
12. shibasaki kou
13. exile
14. pornografitti
15. ayaka
16. yui
17. hirai ken
18. yuki
19. kuwata keisuke
