^ Yeah, it's really not fair to compare in that sense. Honestly I just looked at the number of songs Ayu has available and I practically spit out my drink. lol I remembered from before that the difference is big, I just didn't remember it being this big.
Ayumi: 1,355. Namie: 162. Utada: 117
Then when you look at the top 5 of the overall chart it is even more eyepopping:
1. Exile: 338
2. Greeen: 50
3. Arashi: 79
4. Ayumi: 1,355
5. Nishino Kana: 32
It's like geez, calm down Avex!
Not saying that is bad for Ayu, but at least extremely impressive for everyone else to rank that highly with such few songs.
